Question 24

Cost of Sugar (C12H22O11) is ₹40 per kg; calculate it's cost per mole.

Answer

Molar mass of C12H22O11 = 12C + 22H + 11O = (12 x 12) + (22 x 1) + (11 x 16) = 144 + 22 + 176 = 342 g

1000 g of sugar costs = ₹40

∴ 342 g of sugar will cost = 401000\dfrac{40}{1000} x 342 = ₹13.68 per mole
