## How many moles of NaCl are present in?

So, the molar mass of NaCl = 35.5 gmol−1 +23 gmol−1= 58.5 gmol−1. Now, we have to use the following formula to calculate the number of moles of NaCl. The mass of NaCl is given as 20g. So, the number of moles of NaCl present in 20 g of NaCl is 0.342 mol.

## How many grams of NaCl should be dissolved for 250cm3?

Given, volume of solution is 250ml or 0.25 liter. So, number of mole of solute (NaCl) is 0.125mole present in solution . Hence, 7.3125 grams of sodium chloride is present in 250mL.

## 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 many moles and grams of NaCl are present in 250 mL of 0.5 M NaCl solution?

From this we can conclude that the number of moles and grams of NaCl present in 250 mL of a 0.5 M NaCl solution is 0.125 and 7.32 respectively.
