Answer. The molar mass of Na2CO3 is 106 g/mole.

## How do you find the moles of Na2CO3?

- The formula of sodium carbonate is Na2CO3 so its molar mass is:
- molar mass = (2χ22.99 (Na)) + 12.01 (C) + 3χ16.00 (O)) g mol-1 = 105.99 g mol-1.
- The mass of sodium carbonate required is therefore:
- mass = number of moles (in mol) χ molar mass (g mol-1)
- = 0.0250 mol χ 105.99 g mol-1 = 2.65 g.

## How many moles are in Mg3N2?

Each molecule of ammonia (NH3) consists of one atom of nitrogen (N) and three atoms of hydrogen (H). To calculate molar mass, recognize that a mole of Mg3N2 will contain three moles of magnesium and two moles of nitrogen.

## How many moles are in NaCl?

One mol of NaCl (6.02 x1023 formulas) has a mass of 58.44 g. Concept 2. The relation between molecular (formula) mass and molar mass Page 4 4 • To obtain one mole of copper atoms (6.02 x 1023 atoms), weigh out 63.55 g copper.

## How do I calculate moles?

- First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
- For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.

## How do you calculate the number of moles?

The unit is denoted by mol.

- The formula for the number of moles formula is expressed as.
- Given.
