Question

calculate the volume of 7.2×10²⁰ no. of molecules of SO2 gas​

Answer 1

Answer:

7.2×10^20

720000000000000000000

number of molecules of SO2 gas

Answer 2

Answer:

Correct option is

A

6.0×10

23

The molar mass of SO

2

is 32+16+16=64g/mol.

The number of moles of SO²

present in 64 g of SO²

is

64

64 =1mol.

1 mole of any substance contains avogadro's number of molecules which is 6.0×10²³

.

Thus, the number of molecules of SO²

present in 64 g of SO²

is 6.0×10²³

.
