Question

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

Hey dear,

● 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...
