First of all, you have to calculate the formula mass of HCl & MnO2 i.e. Respectively 36.5 & 87...
Okay... So 4 moles = 4×36.5 = 146 gm of HCl reacts with 1 mole =87 gm of MnO2.... Hence 5 gm of MnO2 reacts with (146×5) ÷87 = 8.39 grams of HCl... SOLVED

but we are not supposed to solve by finding the mass
HCl is aq solution & MnO2 is in solid state so u can't solve it using volume
