## How do you find the number of moles?

To find the number of moles in a sample, **simply weigh it and divide the weight by the molecular weight**. The quotient is equal to the number of moles.

## How many is 2 moles?

after the 19th-century chemist Amedeo Avogadro, is the number we use in chemistry to represent macroscopic amounts of atoms and molecules. Thus, if we have 6.022 × 10 ^{23} O atoms, we say we have 1 mol of O atoms. If we have 2 mol of Na atoms, we have 2 × (6.022 × 10 ^{23}) Na atoms, or **1.2044 × 10 ^{24} Na atoms**.

## What does n m/m mean?

n = m/M n is the **amount of substance**, in moles, mol. m is the mass of the substance, in grams, g. M is the molar mass of the substance (the mass of one mole of the substance) in g mol-1. Molar masses: These. will be given in.

## What is a mole in chemistry?

The mole is **the amount of substance of a system which contains as many elementary entities as there are atoms in** 0.012 kilogram of carbon 12; its symbol is “mol”. … Notice that the definition of the mole is an amount of substance. We will often refer to the number of moles of substance as the amount of the substance.

## How many moles are in 50 liters?

and how many molecules are in 50 liters? 5 moles = 22.4*5 = 112 liters;We need to know how many moles are in 50 liters:50/22.4 = **2.23 moles**; 2.23 moles * 6.022*10^{23} mol^{–}^{1} = 13.44 * 10^{23} molecules.

## What is mole of water?

A mole is a unit measuring the quantity of anything. Water (H_{2}O) is made from 2 atoms of hydrogen and 1 atom of oxygen. A mole of water molecules would be **2 moles of hydrogen atoms plus 1 mole of oxygen atoms**. weight of water = 2(1.0079) g + 15.9994 g. weight of water = 2.0158 g + 15.9994 g.
