Question

the molecular mass of SO2 is 64
a) find the mass of 1Gmm SO2
b)find the number of molecules in 1GMm S02
c) find out the number of molecules in 320g of SO2​​

Answer 1

Answer:

The molar mass of SO

2

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

The number of moles of SO

2

present in 64 g of SO

2

is

64

64

=1mol.

1 mole of any substance contains avogadro's number of molecules which is 6.0×10

23

.

Thus, the number of molecules of SO

2

present in 64 g of SO

2

is 6.0×10

23

.
