Equation for given reaction is as follow,

                             CaC₂  +  2 H₂O     →    C₂H₂  +  Ca(OH)₂

According to eq,

                    64.10 g of CaC₂  produced  =  26.04 g of C₂H₂
So,
                   90.0 g of CaC₂ will produce  =  X g of C₂H₂

Solving for X,
                              X  = (90.0 g × 26.04 g) ÷ 64.10 g

                              X  =  36.56 g of C₂H₂
