Jawaban LKM KF Kelompok 4 :a. Massa A = mol A . massa molar A
= 0,17 mol . 55 gr/mol=9,35 gram
Massa B = mol B. massa molar B = 0,80 mol . 18 gr/mol = 14,40 gram
Massa total = 9,35 gram + 14,40 gram = 23,75 gram
Persen berat A = massa A
massa A+massa Bx100%

x100%
= 39,37 %
Persen berat A = massa B
massa A+massa Bx100%
= 14,423,75
