Question

The cost of per mole of sugar(C12H22O11)is Rs 20, how moch a pocket of sugar containing 2kg would cost?

Answer 1

Molecular mass of sugar= (12×12) + (1×22) + (16×11)=342g/mol

number of moles= given weight (in g)/molecular mass= (2000/342) moles

1 mole costs Rs. 20

(2000/342) moles will cost (2000×20)/342 ≅ Rs.117
