Question

Calcelate the Number of GMM and the
Number at Molecules in 44 g co2 (Atomic mass C=12 , O=16)​

Answer 1

Answer:

Gram molecular weight of CO

2

= 12+2 × 16 = 44g.

Now, 44g of CO

2

contains 6.023×10

23

molecules.

∴ 11g of CO

2

contains =

44

6.023×10

23

×11

= 1.51×10

23

molecules.

Answer 2

Answer:

O=16

Explanation:

therefore, 16-12

= 4 is answer of this question
