How do you calculate 1 mole of NaCl?
If you had the compound sodium chloride (NaCl), you would add the mass of 1 mol of sodium and 1 mol of chlorine. This would give you the mass of 1 mol of sodium chloride which would be about 58.443 g.
How do you calculate moles from molarity?
To calculate the number of moles in a solution given the molarity, we multiply the molarity by total volume of the solution in liters.
How do you find 1 mole of Na?
How many atoms are in a 3.5 g sample of sodium (Na)? 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.
How many moles are in HCl?
Using periodic table you can find molar mass of HCl, which is 36.458 g/mol. This means 1 mol of HCl is 36.458 grams. So 20 g of HCl is 0.548 mol.
