## How do I calculate moles?

Use the molecular formula to find the molar mass; to obtain the number of moles, divide the mass of compound by the molar mass of the compound expressed in grams.

## Which has more Formula Units 1 gram NaCl or 1 gram of KCl?

Answer. This is because the Potassium atom (K) is heavier than the Sodium atom (Na). Thus one gram of NaCl will contain more molecules (formula units) than one gram of KCl.

## How many grams are in 3.3 moles of potassium?

In 3.3 moles of potassium sulphide (K2S), there are 363.99 g. Let’s first calculate the molar mass of K2S (Mr) which is the sum of atomic masses (Ar) of its elements. According to the periodic table, Ar(K) = 39.1 g/mol and Ar(S) = 32.1 g/mol. Mr(K2S) = 2Ar(K) + Ar(S) = 2 * 39.1 + 32.1 = 110.3 g/mol.

## What is a 1 mole?

A mole is defined as 6.02214076 × 1023 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.
