Thus for convenience of measurement we generally express the mass of the carbon atom is [12g]. From the above concept of mole we tell that one mole of carbon contains [12g] of carbon, which is the molar mass of carbon. So the amount of carbon present in [2] moles of carbon =[2 times 12{text{ }}g = 24g].

## What is the mass of two moles of carbon-12?

According to the periodic table the mass of one mole of carbon is 12, therefore two moles of carbon atoms is : 2 mole × 12g/mol = 24 g of carbon atoms.

## What is the molar mass of 2 mole of carbon?

We are given the mass of the sample and look up the molar mass of carbon in the periodic table which is 12.01g/mol.

## What is the mass of carbon-12 mole?

The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).

## How do you find the mass of 2 moles of carbon?

From the above concept of mole we tell that one mole of carbon contains [12g] of carbon, which is the molar mass of carbon. So the amount of carbon present in [2] moles of carbon =[2 times 12{text{ }}g = 24g].

## 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 2 carbon?

The mass spectrometer reports that there are two isotopes of carbon, 98.99% of the sample has a mass of 12 amu (not a surprise since this is the atom on which the scale is based). The average mass is simply a weighted average.

## How do you find the mass of carbon?

To calculate the mass of a single atom of carbon, we just need to divide the molar mass of 12.0 g (0,012 kg) by the number of particles per mole (Avogadro’s number). Doing so yields 1.99 ´ 10^{–}^{26} kg as the mass of a carbon atom.
