## How many moles of CO2 are present in 12.4 g of CO2?

There are **0.2872 mol** CO2 in 12.64 g CO2 .

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

There are **3.6132 x 1024 oxygen atoms** in exactly three moles of carbon dioxide.

## How do you find moles of CO2 produced?

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.

## What is the mass of 3 moles of carbon dioxide?

so in 3mole it is **132gram**.

## Why is the mole based on carbon-12?

Carbon-12 is the basis for the mole **because the atomic mass of 12 grams of Carbon-12 is exactly the Avogadro’s number which defines a mole**.

## What is the mass of carbon-12 in grams?

**1.992×10−23 gm**.
