Question

Arjun purchased 250 g of glucose (C6H12O6) For Rs 40. Find the cost of glucose per mole.

Answer 1

Answer:

Molecular formula of glucose is C6H12O6.

The molecular mass of glucose = 6 × atomic mass of C + 12 × atomic mass of H + 6 × atomic mass of O  

= 6 × 12 + 12 × 1 + 6 × 16  

= 72 + 12 + 96  

= 180 g/mol  

The mass of one mole of glucose is 180 g

Cost of 250 g of glucose is  = 40 Rs

Then cost of 1 g is 250/40 which is 6.25 Rs

so, price of 180 g of glucose is = 180/6.25 =  28.8 Rs.
