Question

How many moles of acetylene should Ms Xiyao produce?

Answer 1

Solution

Acetylene (C₂H₂)is formed by the reaction of Calcium carbide (CaC₂) and water given by the following equation;

CaC_2(s) + 2H₂O_(l) = C₂H_2(g)+ Ca(OH)_2(aq)

1 mole at STP= 22.4L

Moles prepared to produce 10L

$\frac{1mole\times10L}{22.4L}= 0.446 moles$

Moles of acetylene produced

=0.446 moles
