Why are moles not grams?

A mole of atoms is a collection of atoms whose total weight is the number of grams equal to the atomic weight. An equal number of moles of different elements contains equal number of atoms, so it is convenient to express amounts of elements in terms of moles, rather than in terms of grams.

Why do you convert moles to grams?

Mole is the standard unit of amount measurement. Substances react in simple ratios of moles. But, when you have to compare the amount of one substance to another by moles, you must convert into grams since balances do not provide readings in moles. You have three steps to convert mole values to grams.

Can moles be converted to grams?

In order to convert the moles of a substance to grams, you will need to multiply the mole value of the substance by its molar mass. Now, use the number of moles and multiply it by the molar mass.

Does g mol mean grams per mole?

The mass of one mole of atoms of a pure element in grams is equivalent to the atomic mass of that element in atomic mass units (amu) or in grams per mole (g/mol). Although mass can be expressed as both amu and g/mol, g/mol is the most useful system of units for laboratory chemistry.

How do I convert from grams to moles?

Divide the number of grams of the compound, NaOH, by the molecular weight and as a result, the grams (g) unit cancels and all we have left is the unit mol (moles).

How do you work out the number of moles?

So in order to calculate the number of moles of any substance present in the sample, we simply divide the given weight of the substance by its molar mass. Where ‘n’ is the number of moles, ‘m’ is the given mass and ‘M’ is the molar mass.

What does g mol mean?

Molar mass
Molar mass is defined as the mass in grams of one mole of a substance. The units of molar mass are grams per mole, abbreviated as g/mol. The mass of a single isotope of any given element (the isotopic atomic mass) is a value relating the mass of that isotope to the mass of the isotope carbon-12 (

What is gram mole?

(Often called gram-molecular weight.) A mass of a substance in grams numerically equal to its molecular weight. Example: A gram-mole of salt (NaCl) is 58.44 grams.
