This reactor uses calcium carbide as its hydrocarbon source..........

Explanation:

And follows the stoichiometric equation:

Ca2+[CC](s)+2H2OCa(OH)2+HCCH(g)

We assume you want 1L of acetylene gas under standard conditions of temperature and pressure, which (depending on the standard) is 0 C and 100 kPa

Using the Ideal Gas equation with the appropriate gas constant, we solve for n=PVRT

=1bar×1L8.314×102LbarK1mol1×273.15K

=0.0440mol.

And so we need a mass of ............................................

0.0440mol×64.1gmol1=2.81g with respect to calcium carbide.
