A) H2SO4 w(массовая доля)(H2) = 2/98 = 2.04 %
w(S) = 32/ 98 = 32.65 %
w(O4) = 64/ 98 = 65.3 %
б) H3PO4 w(H3) = 3/98 = 3.06%
w(P) = 31/98 = 31.63%
w(O4) = 64/ 98 = 65.3%
в) Cu(OH)2 w(Cu) = 64/98 = 65.3%
w(O2) = 32/98 = 32.65 %
w(H2) = 2/98 =
2.04 %
г) NH4Br w
(N) = 14/98 = 14.29%
w
(H4) = 4/98 = 4.08%
