Question

What is molarmass? give an example

Answer 1

Calculating Molar Mass. Molar mass is the mass of a given substance divided by the amount of that substance, measured in g/mol. For example, the atomic mass of titanium is 47.88 amu or 47.88 g/mol. In 47.88 grams of titanium, there is one mole, or 6.022 x 1023 titanium atoms.

Answer 2

A mole is a unit of measure that helps us compare particles of any given substance and its mass. If we already know the number of moles needed, we can use the concept of molar mass to calculate how many grams of the substance are required. The molar mass, also known as molecular weight, is the sum of the total mass in grams of all the atoms that make up a mole of a particular molecule. The unit used to measure is grams per mole.

Ex: Compounds are substances that are made up of more than one element. For example, some common compounds include salt, glucose, acetic acid (or vinegar), and sodium bicarbonate (or baking soda).

The compound sodium chloride is made up of two elements, namely, sodium and chlorine. Let's use this compound, sodium chloride, as our first example on how to calculate the molar mass for the compounds. The first thing we need to do is to find sodium and chlorine in the periodic table.

Molar Mass= Grams*Mole
