Convert 7.50 grams of glucose C6H12O6 to moles

0.04167mole

Explanation:

To convert gram to mole,

C6H12O6

C - 12

H - 1

O - 6

There are 6 moles of C, 12 mole of H and 6 mole of O

Therefore, multiply each number of mole by the mass of each element

C - 12 * 6 = 72

H - 1 * 12 = 12

O - 16 * 6 = 96

The molar mass of C6H12O6 = 72 + 12 + 96

= 180g/mol

Dividing the number of mass by the mm

= 7.50g / 180g/mol

= 0.04167 mole
