How many grams of solute are present in 25.0 mL of 0.654 MK2Cr2O7(aq)? (.25 mL)(0.654 mol/1 mL)(294.2 g/1 mol) = 48 gK2Cr2O7

What volume of a 6.0 M nitric acid solution would you need toprepare 125 mL of 0.600 M HNO3(aq)?
6.0 M HNO3 x V HNO3 = (0.600 M HNO3)(125.0 mL)
V HNO3 = [(0.600 M HNO3)(125.0 mL)]/(6.0 M HNO3)
V HNO3 = 125 mL
