Question

What weight if each element is present in 1.5 moles of sodium sulphur (Na2SO3)?

Answer 1

if each element 1.5 moles of sulphur
no of molecules=6.023×10^3×16/

Answer 2

mass of sodium = 23

at a mole 1.5

number of mole = (m) mass of an element/(m.m) molar mass of element.

=1.5/23

=0.065 ans.

mass of Sulphur = 32

at a mole=1.5

no.of mole =m/m.m

=1.5/32

=0.046 ans.

mass of oxygen=16

at a mole=1.5

no.of.mole=m/m.m

=1.5/16

=0.093 ans.
