One mol of NaCl (6.02 x1023 formulas) has a mass of 58.44 g.
How many moles is in salt?
Na is 23.0g and Cl is 35.5g which you add together to get the molar mass of the two is 58.5g/mole. Take the 13.8g of NaCl and divide it by the 38.5g will give you the moles: 13.8g NaCl(1 mole/58,5g)=. 236 moles of NaCl.
Is a mole 1 gram?
The term gram-molecule (g mol) was formerly used for “mole of molecules”, and gram-atom (g atom) for “mole of atoms”. For example, 1 mole of MgBr2 is 1 gram-molecule of MgBr2 but 3 gram-atoms of MgBr2.

What does 1 mole of NaCl weigh?
Multiply the given number of moles (2.50 mol) by the molar mass (122.548 g/mol) to get the grams.
How do I calculate moles?
How to find moles?
- Measure the weight of your substance.
- Use a periodic table to find its atomic or molecular mass.
- Divide the weight by the atomic or molecular mass.
- Check your results with Omni Calculator.
How much is a mole?
A mole is defined as 6.02214076 × 1023 of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
Do moles have eyes?
Moles are small, burrowing mammals. Their eyes are poorly developed, but what they lack in sight, they make up for in their sense of touch. All moles have very sensitive snouts and long, clawed digits that they use to dig tunnels.
How many grams are in 5 moles?
Therefore, 5 moles × 32.0 g/mol = 160 grams is the mass (m) when there are 5 moles of O2 .
How many grams of salt make up 2 moles of salt?
Short answer: 140.4 grams. One mole would be 58.5 grams, or 23 (the atomic mass of sodium) + 35.5 (the atomic mass of chlorine).
How many moles are in table salt?
NaCl (1.00 mol), 58.5 g.
How do you calculate moles of salt?
To convert between grams and moles, you would use the substance’s molar mass. To go from grams to moles, divide the grams by the molar mass. 600 g58.443 g/mol = 10.27 mol of NaCl.
How many grams of sodium are there in 1 mole of NaCl?
The molar mass of sodium (Na) is 22.99 g/mole and the molar mass of chlorine (Cl) is 35.45 g/mole (I got these values from a periodic table) so the molar mass of sodium chloride (NaCl) is 22.99 + 35.45 = 58.44 g/mole.
What is the weight of 1 mole of solute?
One mole equals the molar mass of the solute which is 58.4538 grams.
