Volume rata-rata HCN = 19+21+20/3 = 20
Molaritas Ca(OH)2 = 0,05M
Volume = 20mL
Molaritas HCN
M1V1n1 = M2V2n2
0,05×20×2 = M2 × 20 × 1
2 = 20M2
M2 = 2/20
M2 = 0,1M
massa HCN
M = gr/Mr × 1000/v
0,1 = gr/27 × 1000/20
0,1 = 50gr/27
gr = 0,1×27/50
gr = 0,054
Jadi Massa HCN yang terbentuk adalah 0,054gr
Kunci → [C]
