Web10 nov. 2016 · Explanation: In order to find out how many atoms we have in a certain amount of a sample, we have to use the Avogadro constant: the number of atoms in one mole, N A, is equal to 6.02 ×1023. In order to work out how many moles we have in our sample, we can use the formula n (moles) = m (mass) Mr (molar mass). n = 10 80 = 0.125 WebAgNO3 + NH4Cl —-> AgCl + NH4NO3 (125mL) (0.500M) = 62.5 mol AgNO3 (100mL) (0.300M) = 30 mol NH3Cl (30 mol NH4Cl) / (1000/mol) x (1/1) x 143.32 g AgCl/mol = 4.30 g How many milliliters of 0.260 M Na2S are needed to react with 25.00 mL of 0.315 M AgNO3?
