How do I find density? Measure the object's mass (or weight) in kilograms. Measure the volume of the object in m3. Divide the mass by the volume. You will then have the density of the object in kg/m3. How can I find volume with density and mass? Look up the density of the mate...
Calculate the mass of the H2O produced: (0.4499 mol)(18.015 g/mol) = 8.10495 g which is 8.10 g when rounded to 3 sig figs. Percent Yield: If you are looking for the % yield you would need to compare the actual amount produced (you didn't specify what that was) to the max possibl...
