220 mg of CO2 contains only 0.0050 mol CO2, which is nowhere near 6×10^20 moles. If you subtracted 6×10^20 moles from 0.0050 mol CO2, you would get a negative number of moles. Do you mean molecules of CO2? Use dimensional analysis to calculate moles of CO2 in 0.22 g.

## How many moles are there in 220mg of CO2?

220 mg = 0.22 g. molar mass CO2 = 44.0 g/mol. 0.22 g / 44.0 g/mol = 0.005 mol.

## How many moles of CO2 are present in?

1 mole of CO2 = 6.022 x 1023 atoms = 44g. =1.16 moles.

## How many moles of CO2 are present in 220g CO2 44 g mol?

The molar mass of CO_{2} is 32 + 12 = 44 g. The number of moles of CO_{2} in 220 g of CO_{2} is 220/44 = 5 moles.

## How many moles of CO2 are present in 22 grams?

So, the mass of 1 mole of carbon dioxide is 44 grams. Thus, 22 grams of carbon dioxide are equal to 0.5 mole.

## How many moles of CO2 are in CO2?

Therefore, 2 moles of CO2 = 2×6.022×10^23 = 12.044×10^23 molecules of CO2.

## How do you find moles of CO2?

Calculate the number of moles of CO2 by the formula n=PV/RT, where P is the pressure from Step 3, V is the volume from Step 2, T is the temperature from Step 1 and R is a proportionality constant equal to 0.0821 L atm / K mol.

## How many moles of carbon is in CO2?

Every molecule of carbon dioxide, CO2 , contains one atom of carbon and two atoms of oxygen. This means that every mole of carbon dioxide will contain 1 mole of carbon and two moles of oxygen.

## How many moles are in 28g of CO2?

Mol in 28 g CO2 = 28 g / 44 g/mol = 0.64 mol – 2 significant digits.

## How many moles of CO2 are present in 88.0 grams of CO2?

The molecular weight of carbon dioxide (CO2) is 44 (1 C + 2 O = 12 +32). So, one mole of CO2 has a mass of 44 grams. Divide 88 g by the 44 g/mol and you get 2 moles. Hence the number of moles = 88÷44= 2 moles.
