Answer ALL parts:

A. Vanadium has a body-centered cubic unit cell. The density of vanadium is 6.11 g/cm. Calculate the atomic radius of vanadium in angstroms. (1 = 10 m)

B. The boiling point of pure methanol (CHOH, MM = 32.04 g/mol) is 64.7 C. A solution is made using 100.0 g of methanol (the solvent) and 30.1 g of fructose (MM = 180.16 g/mol). What is the boiling point of this solution, in C? (Kb of methanol is 0.86 C/m)

C.You dissolve a 30.0 g mixture of glucose (CHO) and NaCl in 1.00 kg water. The freezing point of this solution is found to be -0.641 C. Assuming ideal behavior, what is the mass (in grams) of glucose in the mixture? (Kf for water is 1.86 Ckg/mol).

D. The boiling point of pure methanol (CHOH, MM = 32.04 g/mol) is 64.7 C. A solution is made using 100.0 g of methanol (the solvent) and 30.1 g of fructose (MM = 180.16 g/mol). What is the boiling point of this solution, in C? (Kb of methanol is 0.86 C/m)

E. What mass in grams of NH (MM = 17.031 g/mol) would need to be added to 310.1 g of water in order to lower the freezing point of water by 12.0 C? (Kf for water is 1.86 C/m)
