can anyone please help me find out how to work out the following problems..
1.) How many millimeters of 0.510 M NiCl2 contain 1.00 g of solute??

You mean milliLiters, not milliMeters.
A 1 molar solution contains 1 mole of solute in 1 liter (1000 ml) of solution. A 0.510M solution contains... 0.51 moles per liter! Nickel chloride has some molecular weight (I won't look it up), so that 0.510 moles corresponds to some number of grams. Divide 1000 ml/liter by the grams/liter, and you get ml/gram.

CVM= m
C= 0.510 M
V = ?
M = 129.6 g/mol
m = 1 g
We solve for V:
V = m / CM = 1 g / (0.510mol/L)(129.6 g/mol) = 0.0151 L
V = 15.13 mL
Good luck!
