Answer 1

Answer:

sure

Explanation:

percentage composition means amount in percentage of any element present in any compound.

ex, in caco3 we can calculate percentage compostion of ca, c, and oxygen

mass of caco3 is 100

% of ca= 40/100 × 100 = 40%

% of c = 12/100 × 100 = 12%

% of o = 3×16/100×100= 48%

Answer 2

Answer:

The percentage composition of a given compound is defined as the ratio of the amount of each element to the total amount of individual elements present in the compound multiplied by 100.

Explanation:

CO2:

Weight of CO2 = 44

44 grams of CO2 has 12 g of Carbon

100 g of CO2 has: 12 / 44 x 100 = 27% of Carbon

44 grams of CO2 has 32 g of Oxygen

100 g of CO2 has: 32 / 44 x 100 = 72%
