## How do you find the mass of a mole of Na atoms?

In this example, multiply the grams of Na by the conversion factor 1 mol Na/ 22.98 g Na, with 22.98g being the molar mass of one mole of Na, which then allows cancelation of grams, leaving moles of Na.

## What is the mass of atoms of sodium?

## What is the formula for moles 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.

## How many moles are in 10 grams of hydrogen?

1 mole of hydrogen weighs 2g thus 10/2 is the number of moles of hydrogen in 10 gm.

## What is the formula for calculating molar mass?

The characteristic molar mass of an element is simply the atomic mass in g/mol. However, molar mass can also be calculated by multiplying the atomic mass in amu by the molar mass constant (1 g/mol). To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms.

## What mass of sodium is required?

5.25 g. In the question, we are provided by the given mass of Mg and molar mass of both Na and Mg, from where we can find the number of moles for magnesium and thus the required mass of sodium.

## How many atoms are in 2 moles?

If we have 2 mol of Na atoms, we have 2 × (6.022 × 10 23) Na atoms, or 1.2044 × 10 24 Na atoms.
