## What is the mass of a mole?

The molar mass of an element (or compound) is the mass in grams of 1 mole of that substance, a property expressed in units of grams per mole (**g/mol**) (see Figure 3.5).

The Mole.

Element | C |
---|---|

Average Atomic Mass (amu) | 12.01 |

Molar Mass (g/mol) | 12.01 |

Atoms/Mole | 6.022 × 10^{23} |

## How do you find the mass of moles?

A substance’s molar mass is calculated by **multiplying its relative atomic mass by the molar mass constant** (1 g/mol). The molar mass constant can be used to convert mass to moles. By multiplying a given mass by the molar mass, the amount of moles of the substance can be calculated.

## How do you calculate the mass of a mole?

If mass is given in kilograms (kg), **multiply it by 1,000 to** give a mass in grams (g). Substitute in the values and solve the equation to find moles of substances (mol).

## How much is a mole?

A mole is defined as **6.02214076 × 10 ^{23} of some chemical unit**, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

## What is the mass of 4.00 moles of oxygen gas?

4 moles of oxygen gas would be equivalent to 4 moles x 32 g/mole = **128 g**. Thus, 4 moles of oxygen gas (O2) would have a mass of 128 g.

## What is the mass of 4 mole of co2?

Answer:- The Required Answer Is **17.6 Grams**.
