The mass of oxygen in 4 moles of C2H4O2 is 128g.
<h3>How to calculate mass?</h3>
The mass of a substance can be calculated by multiplying the number of moles of the substance by its molar mass.
Molar mass of C2H4O2 = 12(2) + 1(4) + 16(2) = 60g/mol
mass of C2H4O2 = 60g/mol × 4 moles = 240grams
However, the mass of oxygen in the compound can be calculated as follows:
molar mass of oxygen/molar mass of compound × 240 grams
32g/mol ÷ 60g/mol × 240g
= 128g
Therefore, the mass of oxygen in 4 moles of C2H4O2 is 128g.

Hey there!
There is a coefficient of 10 in front of water, and a coefficient of 1 in front of the salt.
This means that for every one mole of salt, there is 10 moles of water.
The mole ratio of salt to water is 1 to 10, or 1:10.
