There are 0.511 moles of CO 2 in 22.5 gm of the substance

Determine the number of moles of carbon dioxide, we need to use the molecular weight of CO₂ and the given mass of 22.5 g.

The molecular weight of CO₂ is:

c = 12.01 gm/mol

o = 16.00 gm/mol

2 x o = 2 x 16.00 gm/mol = 32.00 gm/mol

So, the molecular weight of CO₂ is 12.01 gm/mol + 32.00 gm/mol = 44.01 gm/mol.

Now, we can use the formula:

no of moles = Given mass / Molar mass

where n is the number of moles, m is the given mass, and M is the molecular weight.

Plugging in the values, we get:

n = 22.5 g / 44.01 g/mol

n = 0.511 moles"
