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 0.073% si by mass is used to make a rectangular plate that is 15.0 cm long, 12.5 cm wide, and 2.50mm thick and has a 2.50-cm-diameter hole drilled through its center such that the height of the hole is 2.50mm .
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 and a percent natural abundance of 3.10%
how many silicon-30 atoms are found in this plate?
