The molar mass of the gas that has a mass of 3.82 g and occupies a volume of 0.854 L is 106.66g/mol.
<h3>How to calculate molar mass?</h3>
The molar mass of a substance can be calculated by dividing the mass of the substance by its number of moles.
However, the number of moles of the gas in this question needs to be calculated first using the ideal gas law equation:
PV = nRT
Where;
- P = pressure
- V = volume
- n = number of moles
- T = temperature
- R = gas law constant
1.04 × 0.854 = n × 0.0821 × 302
0.888 = 24.79n
n = 0.888/24.79
n = 0.036mol
Molar mass of gas = 3.82g/0.036mol
Molar mass = 106.66g/mol
Therefore, the molar mass of the gas that has a mass of 3.82 g and occupies a volume of 0.854 L is 106.66g/mol.

Answer:
Biochemistry focuses on the studies of biological matter. ... Medical biochemistry seeks to advance the understanding of chemical structures and processes that constitute health and disease, and underlie transformations between these two states.
Answer:
1.38 mol.
Explanation:
- It is known that every 1.0 mole of a molecule contains Avogadro's number of molecules (NA = 6.022 x 10²³).
<em><u>Using cross multiplication:</u></em>
1.0 mole of H₂SO₄ contains → 6.022 x 10²³ molecules.
??? moles of H₂SO₄ contains → 8.31 x 10²³ molecules.
<em>∴ The no. of moles in (8.31 x 10²³ molecules) of H₂SO₄ </em>= (1.0 mol)(8.31 x 10²³) / (6.022 x 10²³ molecules) = <em>1.38 mol.</em>
