how much of the water (in ml) contains 170 mg of pb? (assume a density of 1.0 g/ml.)
170 mg of Pb is equal to 0.17 g of Pb. Since the density of water is 1.0 g/ml, that would be the same as 0.17 ml of water. So, the answer is 0.17 ml of water contains 170 mg of Pb.
What is density?The density of a substance (volumetric relative density but rather specific mass) is its mass per unit volume. The most common symbol for density is (the lower case Greek letter rho), but the Latin letter D is also an option. It is sometimes modified by the dimensionless value "relative density" as well as "specific gravity," i.e. the ratio of the denseness of the material compared to a standard material, usually water, to simplify density comparisons across different systems of units. As a result, a relative density below one in relation to water indicates that the substance hovers in water.

if a cation forms an insoluble percipitate with cl[AgCl] according to le chatelier's principle which direction is favoredadded to insoluble
According to Le Chatelier's principle, if a cation forms an insoluble precipitate with [AgCl], the direction that is favored when added to the system is for the precipitate to form.
When a cation is added to a solution containing Ag+ ions and Cl- ions, it can form an insoluble precipitate with AgCl if it is one of the cations that are capable of doing so. This will cause AgCl to come out of the solution and form a solid precipitate.
This reaction is exothermic, releasing heat, and the formation of the precipitate will consume Ag+ and Cl- ions, which will decrease the concentration of the ions in the solution.
By consuming the reactants, the formation of the precipitate will cause the reaction to shift to the right, in the direction of the formation of the precipitate. This is in agreement with Le Chatelier's principle which states that a system at equilibrium will shift to counteract the changes imposed on it.

if 1.24 l of a gas is at standard temperature and pressure is compressed to 451 ml, what is the new pressure of the gas in atm (hint, temperature stays the same)?
The new pressure of the gas is 2.75 atm.
Standard temperature and pressure refers to the conditions at temperature 0°C or 273K and pressure 1 atm.
According to Boyle's law, "The volume of a given amount of gas held at constant temperature varies inversely with the applied pressure when the temperature and mass are constant. "
This means that with the increase in volume increases, there will be a decrease in pressure and vice versa.
This gas law equation is represented as:
P₁V₁ =P₂V₂
where,
P₁ and P₂ are initial and final pressure respectively.
V₁ and V₂ are initial and final volume respectively.
Given here,
P₁= 1 atm
V₁= 1.24 L
V₂= 451 ml = 0.451 L
To find: P₂
using the equation,
P₁V₁ =P₂V₂
⇒1 × 1.24 L = P₂ × 0.451 L
⇒ P₂ = 2.75 atm
Thus, the new pressure is 2.75 atm

An element in which the highest occupied s and p sublevels are filled is called a noble gas or an inert gas.
The noble gases are a group of elements in the periodic table that are located in the far right column, these elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
The noble gases have a full valence shell, meaning that their outermost electron shell is filled with the maximum number of electrons. This gives them a stable electron configuration and makes them unreactive with other elements. Because of this, they are also referred to as "inert" gases.
Noble gases are chemically unreactive due to their filled valence shells, which makes them a unique group of elements and they are used in a wide range of industrial and medical applications.

Sodium chloride can be made as follows: 2Na + Cl2 → 2NaCl
Calculate the maximum amount of NaCl possible if 2.3 g of sodium was reacted with excess chlorine. Show all your workings
(Ar Na = 23, Ar Cl = 35.5)
The maximum amount of NaCl possible would be 5.85 grams.
Stoichiometric problemFrom the balanced equation of the reaction, the mole ratio of sodium that reacts to sodium chloride that is formed is 1:1. Thus, the first thing would be to convert the mass of the sodium given to its mole equivalent.
Mole = mass/molar mass
Mole of 2.3 g sodium = 2.3/23 = 0.1 mol
Since the mole equivalent of the sodium that reacts is 0.1, the mole equivalent of the sodium chloride that is produced will also be 0.1 since the mole ratio is 1:1.
Thus, the mass of 0.1 mol sodium chloride can be deduced as follows:
Mass = mole x molar mass
Molar mass of NaCl = 23 + 35.5 = 58.5 g/mol
Mass of 0.1 mo of NaCl = 0.1 x 58.5
= 5.85 grams.
In other words, the maximum amount of sodium chloride that can be formed from the reaction of 2.3 g of sodium with excess chrlorine will be 5.85 grams.
