Question

volume of 3.2 gram atom of oxy

Answer 1

Answer:

2.24 liters

Molecular mass of oxygen molecule , M.M = 32 g . Now , we know volume of 1 mole of gas at S.T.P is 22.4 liters . Therefore , the volume of 3.2 gram atom of oxygen at S.T.P is 2.24 liters .

Answer 2

Answer:

2.24 liters

Explanation:

Given :

Oxygen's mass, m, is 3.2 g.

To Find :

the 3.2 gramme oxygen atom volume at STP.

Solution :

Molar weight of an oxygen molecule,

$M.M = 32 g$

The amount of oxygen in moles is thus:

$n=3.2/32=0.1moles$

We now know that 1 mole of gas has a volume of 22.4 litres at STP.

0.1 mole of oxygen has the following volume at STP:

$V=22.4*0.1\\V=2.24liters$

3.2 grammes of oxygen have a capacity of 2.24 litres at standard temperature and pressure.
