In a chemical reaction, you collect 1 l of hydrogen gas at stp. how many moles of hydrogen gas did you collect? a) 0.004 b) 0.002 c) 0.02 d) 0.04

Based on the constants and the different standard conditions, each mole of any gas will occupy a volume of 22.4 L with the assumption that the gas is an ideal gas. From the given, there is 1 mole of nitrogen gas. We multiply this number of moles by the Avogadro's number, obtaining 6.022 x 10^23. Thus, the answer is letter B.
