Mass calculation

Calculate mass of ammonium sulphate that can be produced from 70g of ammonium hydroxide

find the mr of ammonium hydroxide
then find moles using moles=mass/mr
then write out the balanced equation for ammonium hydroxide -> ammonium sulfate:
2 NH4OH + H2SO4 -> (NH4)2SO4 + 2 H20
because the ration is 2:1, divide the number of moles by 2
then find the mr of ammonium sulfate and find mass using the same equation
