The densities of magnesium and palladium are 1740 kg/m3 and 11900 kg/m respectively [This data was taken from www.webelemen om.] Convert these densities to units of g/mL. 2. type of metal you used in the experiment. If the cylinder used in this experiment had been made of magnesium, but had the same mass, would it have been bigger smaller? If cylinder used in this experiment had been made of but had the same mass, would it have been bigger or smaller?

Homework Answers
We know 1 kg =1000 gm
1 m^3=1000L=10^6 ml
So...1740kg/m^3=1740*10^-3 gm/ml
And for palladium its 11900*10^-3gm/ml

()UESTIONS 1. If you had used a different mass of magnesium metal, would you expect the empirical formula of the compound to be the same? Explain. 2. If you had omitted steps 12 and 13 from the experiment, how would this omission have affected your results in terms of the empirical formula of the magnesium oxide? In other words, would the ratio of the magnesium to the oxygen have been greater or less than the obtained ratio? 3. From the...

Q3) A drug compound for anticancer treatment, Platinol has a base structure of Pt(NH3)2Cl2. A variant form of the drug has the formula Pt2(NH3)4Cl3. For the variant form, calculate the mass percent of platinum. hint: Molar masses used Pt 195.084g/mol, N 14.0067g/mol, H 1.008g/mol, and Cl 35.453 g/mol.
