m(H2SO4) = 10 g
m(Ba(OH)2)-?
m(BaSO4)-?
H2SO4+Ba(OH)2-->BaSO4+2H2O
M(H2SO4) = 98 g/mol
n(H2SO4) = m/M = 10 / 98 = 0.1 mol
n(H2SO4) = n(Ba(OH)2 = n(BaSO4) = 0.1 mol
M(Ba(OH)2) = 171 g/mol
m(Ba(OH)2) = n*M = 0.1 * 171 = 17.1 g
M(BaSO4) = 233 g/mol
m(BaSO4) = n*M = 0.1 * 233 = 23.3 g
ответ 17.1 г , 23.3 г
