We use the quotient.....#"Mass"/"Molar mass"="Number of moles..."#

And so for $"water"$ we gots....

$(130*kgxx10^3*g*kg^-1)/(18.011*g*mol^-1)=7218.2*mol$

And for $"nitrous oxide"$ we gots....

$(4.6*g)/(44.01*g*mol^-1)=??*mol$

And for $"sulfur dioxide"$ we gots....

$1.82*molxx64.07*g*mol^-1=??*g$

And for $"methylene chloride"$ we gots....

$0.0484*molxx84.93*g*mol^-1=??*g$

Do you see what I have done with the quotient?
