Question

Cost of fructose (fruit sugar) $\left(C_6{H}_{12}{O}_6\right)$ is Rs 80 per kg. Calculate its cost per mole.

• A. Rs 14.4
• B. Rs 12.3
• C. Rs 18.0
• D. Rs 16.7

Answer 1

The correct option is A

Rs 14.4

Gram molecular mass of 1 mole of Fructose

= 6(C) + 12(H) + 6(O)

= 6(12) + 12(1) + 6(16)

= 72 + 12 + 96

= 180 g = 0.18 kg

Cost at the rate of Rs 80 per kg

= 0.18 $\times$ 80 = Rs 14.4
