Frequent question: How many moles are present in 10 5 grams of NaCl?

0.125 mol; 7.32 g.

How many moles are in 5g of NaCl?

Molar mass of sodium chloride is 22.99 g/mol (Na+) + 35.45 g/mol (Cl-) = x g/mol. Then take the mass of sodium chloride sample 5 grams and divide by molar mass to get the number of moles. Take this number and multiply it by Avogadro’s number (6.22*10^23 molecules/mol).

How many moles are present in NaCl?

One mol of NaCl (6.02 x1023 formulas) has a mass of 58.44 g.

How do you find moles from grams of NaCl?

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 moles is 55g of NaCl?

The molecular weight of Na and Cl are 23 and 35.5 g/mol respectively. The molecular weight of NaCl = (23 +35.5) = 58.5g/mol. The moles of the sample is 23.4 moles.
