Question

Define molar volume. Calculate the number of moles and molecules of carbon dioxide gas in a volume
of 89.6 dm^3 measured at STP.​

Answer 1

Answer:

The molar volume of a gas expresses the volume occupied by 1 mole of that respective gas under certain temperature and pressure conditions.

Answer 2

Answer:

molar volume is defined as volume occupied by one mole of a substance at a given temerature and pressure.

The malar volume of carbondioxide is 24 dm^3

then number of moles of carbondioxide is =89.6/24

=3.73moles

no of molecules of carbondioxide is

=3.73×6.022× 10^23

=2.25×10^24

( as 1mole of substance =6.022×10^23 molecules of that substance)
