## How many moles are in 24g of magnesium?

Moles of elements

Because magnesium atoms each have twice the mass of carbon atoms ( ^{24}Mg compared with ^{12}C), **one mole** of magnesium has a mass of 24 g.

## How many grams per mole is magnesium?

For example, one atom of magnesium weighs 24.31 amu (atomic mass units). However, one mole of magnesium weighs **24.31 g**.

## How many moles are in 48 grams of magnesium?

Now, coming back to the formula to find the number of atoms. Therefore, number of atoms in 48 g of Mg = **2 mol** $ times $ $6.022 times {10^{23}}$atoms/mol= [12.04 times {10^{23}}] atoms. Thus, 48 g of Mg is equivalent to $12.04 times {10^{23}}$ atoms.

## What is the mole formula?

Avogadro’s number is a very important relationship to remember: **1 mole = 6.022×1023 6.022 × 10 23 atoms**, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).

## How many grams are there in 1 mole of carbon?

The value of the mole is equal to the number of atoms in exactly **12 grams** of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).

## How many grams are in 1 mole of oxygen?

For one gram atomic weight of oxygen with atomic weight of 16 grams, **one mole** of oxygen also contains 6.022 × 10^{23} oxygen atoms. Similarly, for one gram atomic weight of silicon with atomic weight of 28 grams, one mole of silicon still contains 6.022 × 10^{23} silicon atoms.

## How many moles of MGO are in mg?

Mass magnesium = 2.39 g. Mass magnesium oxide = 3.78 g. So mass oxygen = 1.39 g. Number moles Mg = 2.39/24 = **0.0995**.

## How many moles does boron have?

Boron has two naturally occurring isotopes: ^{10}B (mass = 10.012938 g/mole) and ** ^{11}B** (mass = 11.009305 g/mole). The atomic weight on the periodic table for boron is 10.811 g/mole.

## How many moles of magnesium phosphate contains?

Hint:Magnesium phosphate has **3 moles** of magnesium, two moles of phosphorus and eight moles of oxygen atom in its chemical formula. Because there are three magnesium atoms, two phosphorus atoms and eight oxygen atoms in magnesium phosphate molecules.
