mole.​

Answer 1

Answer:

no of moles= weight÷ GMW

0.72÷180

Okkk.

do division

6×12+12+6×16

72+12+96

84+96

180

Answer 2

Answer:

0.004 mol

Explanation:

Given :

Given mass of glucose = 0.72 g

We are asked to find numbers of moles.

We have chemical formula of glucose.

i.e C₆H₁₂O₆

Molar mass of glucose = ( 12 × 6 ) + ( 1 × 12 ) + ( 16 × 6 )

Molar mass of glucose = 180 g / mol

We know :

No. of moles = Given mass / Molar mass

Putting values here we get :

No. of moles = 0.72 / 180 mol

No. of moles = 72 / 18000 mol

No. of moles = 4 / 1000 mol

No. of moles = 0.004 mol

Hence we get required answer.
