3.42g of sucrose contains_number of carbon atioms

Answer»

Mole of SUCROSE = 3.42/342 = 0.01
number of atom of sucrose = 6.02×10∧23*0.01 = 6.02×10∧21
one sucrose atom CONTAIN 12 CARBON atom
so number of carbon atom in 3.42g of sucrose = 12×6.02×10∧21
                                                                   = 72.24×10∧21
