If a sample of pure cadmium has a mass of 18.2 grams, how many moles of cadmium are in the sample?
2 answers
moles = grams/molar mass.
moles=mass/ram
then,
moles=18.2g/112.411=0.1619
therefore 18.2g of pure Cd = 0.1619 moles
then,
moles=18.2g/112.411=0.1619
therefore 18.2g of pure Cd = 0.1619 moles
