a. 230 g
b. 36 g
c. 23 g
d. 4.6 g
Answers
Answer:
answer will be b
Explanation:
mole is given 0.20
you have to find mass so just convert it into mass
remember if you move away from mole you multiply and if you move towards mole you divide so
just multiply mole with molar mass of glucose
so
0.20×180 = 36 grams

H = 1.01 g/mol, O = 16.00 g/mol
How many moles of LICIO4 are present?
[?] mol LICIO4
Answers
Answer:
The number of moles of H₂O is 0.135 mol.
The number of moles of LiClO₄ is 0.0449 mol.
Explanation:
Mole is an important standard unit used for the measurement of large quantities of atoms, molecules, or other particles. One mole is equal to 6.022×10²³ units.
The number of moles of a substance is calculated by:
[tex]\frac{mass of substance}{molecular weight of substance}[/tex]
To find the number of moles of H₂O:
Mass of H₂O in the sample = 2.43g
The molecular weight of H₂O = 18.02g
Number of moles = [tex]\frac{2.43}{18.02}[/tex] = 0.135 mol.
To find the number of moles of LiClO₄:
Mass of LiClO₄ given = 4.78g
The molecular weight of LiClO₄ = 106.39g
Number of moles = [tex]\frac{4.78}{106.39}[/tex] = 0.0449 mol.

How many grams of Al2O3 form
from 54.0 g Al?
[?] g Al₂O3
Answers
Answer:
102 g Al₂O₃
Explanation:
To find the mass of Al₂O₃, you need to (1) convert grams Al to moles Al (via molar mass), then (2) convert moles Al to moles Al₂O₃ (via mole-to-mole ratio from reaction coefficients), and then (3) convert moles Al₂O₃ to grams Al₂O₃ (via molar mass). It is important to arrange the ratios in a way that allows for the cancellation of units. The final answer should have 3 sig figs to reflect the given values.
Molar Mass (Al): 26.98 g/mol
Molar Mass (Al₂O₃): 101.96 g/mol

The 225 g FeCl2 is about 1.8 moles.
What is the molar concentration of
the solution if the total volume is
450 mL?
Answers
Answer:
[tex]4 \frac{mol}{l} [/tex]
Explanation:
From the question, we have been asked to find the molarity of FeCl2 having a volume of 450 mL,
We have been provided with 225 g which is proportional to 1.8 moles.
We know that molarity of any solution should be in mol/L.
1 mole contained in 1 L means it has a molarity of 1 mol/L
Let's convert 450 mL to Litres which is,
[tex] \frac{450}{1000} litres[/tex]
= 0.450 L
Thus,
1 mole is contained in 1L
x moles are contained in 0.450 L
Hence,
x mole/molarity = {1 mole x 1 L}/{0.450 L}
= 4 mol/L
Therefore 4 mol/L is the molar concentration.
