Question

How many molecules in 30g of Each (b) H₂O (a) Co^2​

Answer 1

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:

Explanation:

No of molecules= mole x NA

(6 x 12) + (1 x 12) +(6 x 16)

72 + 12 + 96

180

6.022 X 10^23 x 30 / 180

= 1.003
