Question

Find the moles and mass in 1.12 litre of ozone at STP

Answer 1

Answer:

Explanation:

OZONE= O3

MOLECULAR MASS OF OZONE=48 G

WE KNOW THAT, UNDER STANDARD CONDITIONS OF TEMPERATURE AND PRESSURE,

I MOLE= 22.4 LITRE

GIVEN 1.12 LITRES,

MOLES=1.12/22.4

            =0.05 MOLES

I MOLE= 48 G

0.05 MOLES=2.4 G

THEREFORE,

NUMBER OF MOLES= 0.05

MASS =2.4 G.

HOPE THIS HELPS.

Answer 2

Answer:

0.05

Explanation:

since 22.4 L of gas contain 1 mole at stp

then 1.12 L of gas contains =1.12/22.4 moles

= 0.05
