Molar solutions: 6) How would you make 2000ml of a 2M (molar) solution of sodium chloride? The molecular weight of sodium chloride is 58.44. 7) How much of a 10μM (micromolar) solution would you use to make a solution with a final volume of 50μl (microliters) with a final concentration of 0.5µM? Weight/Volume (w/v) and Volume/Volume (v/v) solutions: 8) If you added 6g of sodium chloride to a final volume of 120ml, what % (w/v) sodium chloride is that solution? ||

Weight/Volume (w/v) and Volume/Volume (v/v) solutions: 8) If you added 6g of sodium chloride to a final volume of 120ml, what % (w/v) sodium chloride is that solution? 9) If you had a stock of 100% ethanol and wanted to make 250ml of a 70% ethanol solution (in water), how would you make it? 10) How much agar powder would you add to 750ml of growth medium if you wanted the final % (w/v) of agar to be 1.5%?
