Question

calculate the change in percentage of C of atoms when all H atoms in methane (CH4) are repalced by t (given atomic weight c-12 h-1 T-3)

Answer 1

Answer:

Amu/Atom amu for this element in the compound. c.=1×12=12 amu .h.=4 ... Next, to find the percentage composition of methane, CH4, we will divide the total mass of.... by the total mass of the compound.

Answer 2

Answer:

25%

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%
