## What is the mass of one 12 carbon atom?

12 amu

Atomic mass is based on a relative scale and the mass of 12C (carbon twelve) is defined as 12 amu; so, this is an exact number.

**What is the mass in grams of one mole of C-12?**

Answer and Explanation: The mass of one mole of carbon-12 atoms is 12 grams.

**What is the mass of 1 mole of carbon atom?**

12 g.

We have given that one mole of carbon atom weighs 12 g. A mole is defined as exactly equal to 6.022×1023 atoms. So, we know that a mole of carbon contains 6.022×1023 atoms. Therefore, we can write the mass of 6.022×1023 atoms = 12 g.

### What is the mass of 5 moles of carbon-12?

The symbol for carbon is C, and the symbol for grams is g. Therefore, 5 moles of carbon to grams is the same as 5 moles of C to grams, 5 moles of carbon to g, and 5 moles of C to g. Furthermore, the atomic mass of carbon is 12.011. That means that one mole of carbon weighs 12.011 grams (12.011 g/mol).

**What is the mass of one mole of carbon-13?**

The molar mass of carbon-13 is 13 grams per mole. A mole is the number of particles necessary for the number of atomic mass units of a single atom or…

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

A mole is the number of atoms in exactly 12 g of carbon-12. A mole of anything, then, contains as many particles as there are in 12 g of carbon 12. In the early 1800s, scientists realized that atoms and molecules react with each other in whole number ratios.

## What is meant by 1 mole of carbon atom?

(a) A mole can be defined as the amount of a pure substance containing the same number of atoms, molecules or ions as present in exactly 12g of carbon. This refers to the value of 6.022 × 1023 atoms, molecules or ions of a substance. Therefore, a mole of carbon atoms refers to a group of 6.022 × 1023 carbon atoms.

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

1.9926934g.

UPLOAD PHOTO AND GET THE ANSWER NOW! Solution : 1 mole of C-12 atoms = 12 g `=6.022xx10^(23)” atoms”` Thus, `6.022xx10^(23)` atoms of C-12 have mass = 12 g `therefore” 1 atom of C-12 will have mass”=(12)/(6.022xx10^(23))g=1.9926934g. `

**How many moles of carbon-12 are contained in exactly 6 grams of carbon-12?**

1 Answer. There are 0.50 moles precisely .

### Why is the mass in amu of a carbon-12 atom reported as 12.011 in the periodic table of the elements?

Although carbon-12 weighs exactly 12 amu, the periodic table reports that the mass is 12.011 because we are taking into consideration the abundances and masses of the other two carbon isotopes (carbon- 13 and carbon-14).

**How many atoms are there in exactly 12g of carbon-12 element?**

6.022 × 1023 atoms

(a) 6.022 × 1023 atoms are present in 12g of carbon-12 element.

**How many grams are in 1 mole of co2?**

44.01g

Molar Masses of Compounds The molar mass of any compound is the mass in grams of one mole of that compound. One mole of carbon dioxide molecules has a mass of 44.01g, while one mole of sodium sulfide formula units has a mass of 78.04g.

## What is the mass of one atom of carbon 12 in grams?

What is the mass of one atom of Carbon-12 in grams? The mass of 1 mole of C-12 atoms = 12 g 1 mole of C-12 atoms = 6.022 × 1023atoms

**What is the mass of 1 mole of C12 atoms?**

The mass of 1 mole of C-12 atoms = 12 g 1 mole of C-12 atoms = 6.022 × 1023atoms The mass of 1 atom of C-12 = 12 / (6.022 × 1023) = 1.99 × 10-23g

**What is the mass of a mole?**

The mole is the link between the micro world of atoms and molecules to the macro world of grams and kilograms. By definition, N A 12C atoms, i.e. Avogadro’s number, 6.022 ×1023 12C atoms has a mass of 12.00 ⋅ g.

### What is the equivalent mass of C in grams?

By definition, N A 12C atoms, i.e. Avogadro’s number, 6.022 ×1023 12C atoms has a mass of 12.00 ⋅ g. But wait a minute! When I look at the Periodic Table, it gives the equivalent mass of C as 12.011 ⋅ g ⋅ mol−1. Why is there a discrepancy?
