An empty beaker weighs 39.17 g.
a) When completely filled with water, the beaker and its contents have a total mass of 406.25 g. What volume does the beaker hold? Use d =1.00 g/mL as the density of water.
for A i got 367.08 but I don't know for this
b) How much would the beaker and its contents weigh if it was completely filled with mercury? The density of mercury is d =13.5 g/mL..
mass with Hg multipy 367.08*13.5 grams
