Question

Calculate the number of moles in 11 g of CO2

Answer 1

given mass=11g

molecular mass =co

12+16*2

12+32

44

m/M

11/44

0.25

Answer 2

no.of moles=given mass/molar mass

molar mass of CO2

=12*1+16*2

=12+32

=44g

no.of moles=11/44

=1/4

=0.25 moles

hope this helps u mark this as branliest
