Use only dimensional analysis to solve this problem. Include a number, unit, and substance in thenumerator and the denominator for every conversion fraction used.Methanol, CH,OH and acetonitrile, CH;CN are both liquids at room temperature. A solution isprepared by dissolving some methanol in acetonitrile (the solvent). This solution is 16.67% (v/v) inmethanol. The density of methanol is 0.791 g/ml. What volume of solution is needed to provide60.0 grams of methanol?Ascorbic acid, vitamin C, is a water-soluble vitamin. A solution containing 80.5 g of ascorbic acid,HCH,O, dissolved in 210.0 grams of water has a density of 1.22 g/ml. Calculate the concentrationof ascorbic acid in this solution in the following units:а.mass percentb.molarity
