Question

14, 2.0 g of a sample of sodium chloride contains
0.785 g of sodium and 1.775 g of chlorine. In
another sample, 2.925 g of sodium chloride
was found to contain 1.15 g of sodium and
1.775 g of chlorine. Show that these data are in
agreement with the law of constant proportion.​

Answer 1

Answer:

● Answer explained-

- The law of constant proportion (aka law of definite composition) states that a given chemical compound always contains its component elements in fixed ratio

(I) Ratio of Na/Cl in first salt-

x1 = 0.785/1.215 = 0.6461 ...(1)

(I) Ratio of Na/Cl in second salt-

x2 = 1.15/1.78 = 0.6461 ...(2)

From (1) & (2),

x1 = x2

Thus proved...
