what will be the internal pressure causes by hydrogen gas when 5.00 g of zinc is dissolved in 50 g of concentrated hydrochloric acid if the volume of the container is 250 mL and the container is allowed to cool 20 degrees celcius
Do you know that Zn is the limiting regent. mols Zn = 5/atomic mass Zn = estimated 0.07 mols Zn produces estimated 0.07 mols H2.
Then use PV = nRT and solve for P.
