Question

Calculate the mass of the following: 2 moles of CO2 and 6.022x10^23 molecules of CO2​

Answer 1

1.mass =mole ×molecular mass

molecular mass of CO2 =12+16×2= 44

mass=mole ×molecular mass

=2×44

=88

mass of 2 moles of CO2 is 88g

2.6.022×10^23×44=264.968×10^23

2.

Answer 2

Answer:

mass=mole× molecular mass

= 2×44

=88

mass of 2 moles equals to

2.6.022×10^23×44=264.968×10^23
