Question

What is the mass of oxygen in 88 g of carbon dioxide?

Answer 1

88 g co2 is 2 moles of co2 ( 1 mole co2 = 44 gm) .

Answer 2

Given:

88 grams of carbon dioxide.

To find:

The mass of oxygen.

Solution:

To determine the mass of oxygen in 88g carbon dioxide we have to follow the below steps as follows-

The chemical formula of carbon dioxide is $CO_2$.

The atomic mass of the C atom is 12 grams and the oxygen atom is 16 grams.

Thus, the molecular mass of carbon dioxide is 12+16×2=44 grams.

Thus 44 grams of carbon dioxide has 2×16=32 grams of oxygen.

So, 88 grams of carbon dioxide has 32×2=64 grams of oxygen.

So, 88 grams of carbon dioxide has 64 grams of oxygen.
