Question

What is the volume of the plate?

Monel metal is a corrosion-resistant copper-nickel alloy used in the electronics industry. A particular alloy with a density of 8.80 g/cm3 and containing 0.047 % Si by mass is used to make a rectangular plate that is 15.0 cm long, 12.5 cm wide, and 4.50 mm thick and has a 2.50-cm-diameter hole drilled through its center such that the height of the hole is 4.50 mm . The silicon in the plate is a mixture of naturally occurring isotopes. One of the those isotopes is silicon-30, which has an atomic mass of 29.97376 amu. The percent natural abundance, which refers to the atoms of a specific isotope, of silicon-30 is 3.10%.
