Question

Plz give this question answes?

Answer 1

Answer:

don't know

sorry...........

Answer 2

Answer:

a.)Avogadro number.

b.)

since,12g of c-12 have 1 mole(6.022×10^23)

therefore, 48g have = 4 mole

no.of carbon atom = 6.022×10^23 × 4

c.)

weight of co2 = 12+(16×2) × 6.022 × 10^23

= 44 × 1 amu

weight of h2o = (1×2)+16 × 6.022 × 10^23

=. 18 × 1amu

hence,

co2 have high weight.

Hope it will help you
