Diketahui:
- HCl Pekat 37% > 1L = 1,19 Kg > 36.5 g/mol
Ditanya: V HCl pekat yang diperlukan untuk membuat HCl 2 M 50 ml
maklum abis liburan ilang smua

The moment you say a word of parting, you've already parted.
So long as you and I are both somewhere in this world, we haven't parted.
So long as you don't say it, you haven't parted.

Diketahui = 37%
larutan = 100gr , HCl = 37gr
tiap 1 L = 1,19kg OR 1ml = 1,19gr
36,5 g/mol tabrak sama 37% ---> 37gr / 36.5 gr/mol = mol HCl
Ro = M/V
V = M/Ro
V larutan = 100gr/1,19gr/ml
= 84,03 ml
M = n/V
M HCl = (37gr / 36,5gr/mol) / (84ml / 1000ml/L)
MHCl = 12
Result
V1 M1 = V2 M2
x 12 = 2 x 50
x = 100/12
x = 8,3 ml
