Question

You made 95.41 gram of carbon monoxide, how many moles of carbon did you start with?

Answer 1

The balanced equation for the formation of carbon monoxide from carbon is:

C(s) + CO2(g) -> 2CO(g)

The molar mass of CO is 28 g/mol.

First, we need to calculate the number of moles of CO produced:

moles CO = mass of CO / molar mass of CO

moles CO = 95.41 g / 28 g/mol

moles CO = 3.412 mol

According to the balanced equation, 1 mole of carbon creates 2 moles of CO. As a result, the amount of carbon moles is:

moles C = moles CO / 2

moles C = 3.412 mol / 2

moles C = 1.706 mol

So, the initial amount of carbon was 1.706 moles.
