Chemistry problem help needed!? I need to find out the maximum volume of hydrogen gas at r.t.p using 6.5 g of zinc granules based on this equation. Equation: Zn(s)+H2So4(aq)-----> ZnSo4(aq) + H2(g)

I assume you mean STP.

6..5 g Zn (1 mole Zn/65.41 g)(1 mole H₂/1 mole Zn)

= 0.0994 moles H₂ ------Now, PV = nRT

(1.00 atmospheres)(X volume) = (0.0994 mole H₂)(0.08206 L*atm/mol*K)(298.15 K)

= 2.4 Liters volume H₂ gas ======
