Question

What volume (in mL) of dry hydrogen gas would be collected?

a) 22.4 mL
b) 11.2 mL
c) 33.6 mL
d) 44.8 mL

Answer 1

The volume of dry hydrogen gas collected at STP can be determined using the molar volume of 22.4 L/mol, but without specific details on the number of moles, the exact value can't be provided.

Step-by-step explanation:

The question involves calculating the volume of dry hydrogen gas collected at Standard Temperature and Pressure (STP). Using the information that the molar volume of a gas at STP is 22.4 L/mol, we can determine the volume of hydrogen gas generated in a stoichiometry calculation. Without additional information, such as the number of moles of hydrogen gas produced, we can't provide a direct answer to the question of which volume option (a, b, c, or d) is correct. However, we do know that, by definition, 1 mole of any gas at STP occupies 22.4 liters; thus if 1 mole of hydrogen was produced, it would occupy 22.4 liters, or 22400 mL. Hence, if you have half a mole, it would occupy 11.2 liters (11200 mL), and if you have two moles, 44.8 liters (44800 mL) accordingly.
