Question

What mass of C6H12O6 will contain 0.36 NA atoms.
(Given : gm atomic mass C = 12 gm, O = 16 gm, H = 1 gm)​

Answer 1

Answer:

Molecular formula =C

6

H

12

O

6

Molar mass =6×12+12×1+16×6=180gmol

−1

Moles in 18g of sample=

180

18

=0.1mole

So,moles of carbon present in sample=0.1×6=0.6

Moles of hydrogen=0.1×12=1.2

Moles of oxygen=6×0.1=0.6

No. of atoms present in carbon=0.6×6.022×10

23

=3.6×10

23

No. of atoms present in hydrogen=1.2×6.022×10

23

=7.2×10

23

No. of atoms present in oxygen=0.6×6.022×10

23

=3.6×10

Answer 2

Answer:

0.36 na /na

gives no of moles that is 0.06

mass= no.of moles*180
