## What is a mole of carbon?

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 one mole of carbon-12?

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. Hence, the mass in grams of 1 atom of carbon is 1.993**×**10−23g .

## What is the mass of 1 carbon?

The mass of a single carbon atom is **1.994 x 10 ^{–}^{23} g**.

## How much is a mole equal to?

The value of the mole is equal to **the number of atoms in exactly 12 grams of pure carbon-12** (12 g C = 1 mol C atoms = 6.022 × 10^{23} C atoms). Here some of the language of the current SI definition is incorporated.

## What is a mole of energy?

The joule per mole (symbol: J·mol^{−}^{1} or J/mol) is an **SI derived unit of energy per amount of material**. Energy is measured in joules, and the amount of material is measured in moles. … It is also a SI derived unit of molar thermodynamic energy defined as the energy equal to one joule in one mole of substance.

## What is the mass of 1 mole of oxygen?

Solution — Mass of one mole of oxygen molecule (O2) = molecular mass of oxygen molecule (O2) in gram = **32 g**.

## What is the formula for moles to grams?

Moles to grams example problem

Solution: Find out the molar mass of the substance (hint: you can use Molar mass of the substance alone to calculate molar mass). The molar mass of KClO3 is 122.548 g/mol. **Multiply the given number of moles** (2.50 mol) by the molar mass (122.548 g/mol) to get the grams.

## What is the formula for calculating molar mass?

Method 1 of 2:

Molar mass is the mass (in grams) of one mole of a substance. **Using the atomic mass of an element and multiplying it by the conversion factor grams per mole (g/mol)**, you can calculate the molar mass of that element.
