Question

Calculate the change in percentage of C (by weight) when all Hators are replaced by T in C molecule
(Given atomic weight - C:12, H:1. T:3)
(A) 75%
(B) 50%
(C) 25%
(D) 40%​

Answer 1

Answer:

50%

Explanation:

Answer 2

Answer:

Explanation:

in ch4 , molar wt = 16 g

% of c = 12/16*100 = 75%

in ct4 , molar wt = 24%

% of c = 12/24*100 = 50%

therefore , change in % = 75% - 50% = 25%
