Combustion of n- heptane is
Molar mass of n-heptane is 7*12+16*1 = 100 g/mol
100 g of n-heptane on Combustion gives 7*44 g of Carbon dioxide.
How many grams of n-heptane on Combustion gives 225 g of carbon dioxide.
= 225 g * 100 g/7 *44 g
= 73.05 g
Hydrolysis of calcium carbide is
Molar mass of Calcium carbide is 1*40+2*12 = 64 g/mol
Molar mass of acetylene = 2*12+2*1 = 26 g/mol
64 g of calcium carbide on Hydrolysis gives 26 g of acetylene.
75000 g of calcium carbide on hydrolysis gives ? g of acetylene.
= 75000 g * 26 g/64 g
= 30468.75 g
= 30.5 Kg
