Mr Cu= 63,5; S= 32; O= 16; H= 1
Mr CuSO4.5H2O= (1x 63,5) + (1x 32) +
(4x 16) + 5[(2x 1) + (1x 16)]= 249,5
Mass of 1 m ol CuSO4.5H2O= 249,5 g So t o m ake a 1 M solut ion of copper
sulphat e is needed as m uch as 1 lit er of
In concentrat ed HCl is usually unknown levels
of 36%, density 1.18. Thus the m ass of 1,000 m L of concentrat ed HCl is1.180 g.
In 1180 g of concentrat ed HCl, the am ount of HCl = 36/ 100 x 1180 g = 424.8 g.
In 1 liter (1,000 m L) 1 M HCl solution contained 1 m ol HCl.
The m ass of 1 m ol HCl = 36.5 g.
So to m ake a 1 M HCl solution required 36.5 g HCl, contained in concentrat ed HCl = 36.5 /
