Question

A glucose solution contains 9 g of glucose (C6H1206).
How many atoms of C, H and O are present in it ?
[Ans : (i) 1.806 x 1023 atoms of C and o
(ii) 3.612 * 10 23 atom of H]

Answer 1

Explanation:

9gr of glucose means that 0.05moles of glucose

1 mole of glucose consists 6 mole carbon 6 mole h2 & 3 mole O2

so there r 6 × 6.023 × 10 ^23 × 0.05 atoms of c and o also & 6 × 2×6.023×10^23 ×0.05 moles
