Massa CH3COONa (Mr = 82 ) yang terlarut dalam 10 ml larutan CH3COONa pH = 9 adalah…

maaf kalau salah,tapi kalau menurut aku sih gitu

n = m/mr

n = 30/40 = 3/4 = 0,75

= n/ 1 kg

= 0,75/0,9 = 0,833

δtb = x.

1,555 = x. 0,833

x = 1,87

1,555/2 = 0,7775

0,775 = 1,87.

baru = 0,935

0,935 = mol / 1,2

mol = 0,935. 1,2 = 1,122

massa = 1,122 . 40 = 44,88 gram
