Assuming an efficiency of 31.20%, calculate the actual yield of magnesium nitrate formed from 133.1 g of magnesium and excess copper(II) nitrate.
Mg + Cu(NO3)2 -> Mg(NO3),+Cu
actual yield:

Aaspirin has a density of 1.40 g/cm^3 what is the volume in cubic centimeters of a tablet weighing 320 mg?

Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3
