Calculate the number of moles of sodium hydroxide in 50.0 mL of 2.50 mol/L NaOH.Calculate the number of grams in 50.0 mL of 2.50 g/L NaOH.At your next lab assignment, you are instructed to prepare 250 mL of 0.500 mol/L HCl by dilution of a 6.00 mol/L stock solution. What volume of HCl do you need to measure out to prepare the dilute solution?Wine is 12% by volume ethanol (C2H5OH). What is the molarity of the solution? The density of ethanol is 0.789 g/mL.Vinegar is a solution that is 5% mass acetic acid (CH3COOH). What is the molarity of this solution (assume the density is 1.0 g/mL).An industrial waste lagoon is contaminated with cadmium. The concentration of Cd2+ in the lagoon is 1.2 mg/L. Convert this unit to μmol/L (remember your prefixes).
