Usng the relative atomic masses calculate the molecular mass for CuBr. This is the mass for one mole. I would use RAMs to at least 3 sig figs because 0.500 is to 3 sig figs.
Hence calculate the mass for 0.500 moles, bearing in mind the number of significant figures in 0.500.
how many grams does 0.500 moles of CuBr weigh?
