magnesium react with hydrochloric acid,what is the volume of hydrogen produced at r.t.p when 0.12g of magnesium ribbon react?

balance the equation
Mg+2HCl>>>MgCl2 + H2
so one gets the same number of moles of H2 as moles one used of Mg.
MolesMg=.12/atomicmassMg
volumeH2=molesH2*RTPmolarvolume
Mg+2HCl>>>MgCl2 + H2
so one gets the same number of moles of H2 as moles one used of Mg.
MolesMg=.12/atomicmassMg
volumeH2=molesH2*RTPmolarvolume
