A sample of calcium carbonate has the following percentage composition. Ca =40 %, C =12 % and 0=48 % According to law of definite proportion the weight of calcium in 4 ~g of a sample of calcium carbonate from another source will be (at. no. Ca =40, C =40, C =12,0=16 )

Options

  1. A1.6 10⁻² ~g
  2. B1.6 ~g
  3. C0.1 ~g
  4. D0.2 ~g

Correct answer

B. 1.6 ~g

Step-by-step solution

(A) In 100 ~g of CaCO ₃, 40 ~g Ca is present In 4 ~g of CaCO ₃= 4 40 100 =1.6 ~g of Ca is present.
