A solution of glucose in water is labeled as 10% w/w, what would be the molality and molarity of the solution. Density of solution is 1.2 ml-1

10%w/w solution of glucose in water means 10 g of glucose present in 100g of solution.
Therefore, Mass of glucose is 10g

4 liters of water are added to 2L of 6 molar HCl solutions. what is the molarity of resulting solution ?

Ans: Initial Volume = 2 liters
Number of moles (n) = 6
Number of moles (n) = weight/gram molecular weight
Gram Molecular weight of HCl = 1+ 35.5 = 36.5 grams
Number of moles (n) = We...
