Frm the equation 32g O2 produces **1 mole CO2**.

## How many CO2 are in 3 moles?

There are **1.806 X 1024 molecules** in 3 moles of CO2.

## How many moles are in 88g of CO2?

5 Answers. CO2 – ATOMIC MASS – 12 + 2 x 16 = 44 . HENCE UNDER – 1 MOLE – I.E UNDER 44 gms – – no of oxygen items are – 02 nos. HENCE – UNDER 44 GMS — NO OF MOLES OF O ITEM – 2 ( I.E O2) THEREFORE – UNDER 88 GMS – 2 x 2 i.e. **4 moles** .

## 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 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 fe2s3 are produced when 2 moles of Fe react with 3 moles?

Because the equation is balanced, we know the proportions of iron and sulfur in the reaction. For this reaction, we see that 2 moles of iron reacts with 3 moles of sulfur to form **1 mole** of iron(III) sulfide.

## How many moles of atoms are in 3 moles of CO2?

1 molecule of CO2 = 1 C atom + 2 O atom. So, 3 moles of CO2 contains (3 x 2 x 6.02 x 10*23) O atoms = **3.61 x 10*24 O atoms**.
