How do you find moles of NaCl?
One mole of sodium (Na) is 22.99 g, and 1 mole of chlorine is 35.45 g. For sodium chloride (NaCl) they are in a ratio of 1:1 so the molar mass of NaCl is 22.99 + 35.45 = 58.44 g/mol.
How do you calculate 1 mole of sodium?
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 2.5 moles of NaCl?
Answer: molar mass of NaCl is 58.5 gm/mol.
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 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 moles of Na are there in 1 mole of NaCl?
6.023*10^23 atoms of Na = 1 mol of Na. 6.023*10^23 atoms of Cl = 1 mol of Cl. 6.023*10^23 molecules of NaCl = 1 mol of NaCl.
What is the formula for calculating moles?
Divide the number of grams of each reactant by the number of grams per mole for that reactant. 50.0 g of Na are used in this reaction, and there are 22.990 g/mol. 50.0 ÷ 22.990 = 2.1749. 2.1749 moles of Na are used in this reaction.
What is a mole and how is it calculated?
How is a mole calculated? If you want to know how many moles of a material you have, divide the mass of the material by its molar mass. The molar mass of a substance is the mass in grams of one mole of that substance.
