Answer 2

Given: 1.52kg of glucose.

To find: We have to find the number of moles.

Solution:

The number of moles of 1.52kg of glucose can be determined as follows-

The chemical formula of glucose is $C_6H_{12}O_6$.

The atomic weight of C is 12, H is 1 and Oxygen is 16.

Thus the molecular weight of glucose is 12×6+12×1+6×16=180g.

1.52kg of glucose means 1.52×1000=1520g glucose.

180g of glucose has 1 mole.

Thus 1520g of glucose has 1520/180=9 moles.

Thus 1.52kg of glucose has 9 moles.
