WebDetermine the moles in 20.0 grams of NaCl. Since we know from the periodic table that the mass of one mole of sodium chloride is 58.44 grams, then; Therefore, the number of moles in 20.0 grams of sodium chloride is 0.34. WebWe can solve for the new volume as follows: First, we need to find the number of moles of oxygen in the initial sample: n = m/M where m = 8.00 g (mass of oxygen), and M = 32.00 g/mol (molar mass of oxygen) n = 8.00 g / 32.00 g/mol = 0.250 mol. The initial volume is V1 = 5.00 L. The total number of moles of oxygen in the final sample is:
