At STP 1 mole of any ideal gas occupies a volume of 22.4 L mass of 1 mole of C2H2 = (2 x 12.01) + (2 x 1.008) = 26.036 g So at STP 26.036 g of C2H2 has a volume of 22.4 L density = mass / volume...

1. convert 0.2625 moles to grams using its molecular mass and dimensional analysis. then divide it by its density to get the volume occupied. 2. use ideal gas law. to get the number of moles of the gas. then divide it to 1.643 g.

From what I can see this is simple stoichiometry question that only requires you to use on relationship: concentration = moles/volume (c = n/v) Information about molar mass, density, molar volume and gas constant aren t necessary to solve this problem. You know that in a reaction...
