Question #21612

Sulphuric acid reacts with potassium to form potassium sulphate and hydrogen. Determine the mass of potassium sulphate produced if 6.0g of hydrogen wa also formed

Expert's answer

2K + H

if m(H

n(H

n(H

n(K

m(K

M(K

m(K

_{2}SO_{4}= K_{2}SO_{4}+ H_{2}if m(H

_{2}) = 6 g, son(H

_{2}) = 6 g / 2 g/mol = 3 moles;n(H

_{2}) : n(K_{2}SO_{4}) = 1 : 1;n(K

_{2}SO_{4}) = 3 moles;m(K

_{2}SO_{4}) = n(K_{2}SO_{4}) * M(K_{2}SO_{4})M(K

_{2}SO_{4}) = 39*2 + 32 + 64 = 174 g/mol;m(K

_{2}SO_{4}) = 3 moles * 174 g/mol = 522gNeed a fast expert's response?
