Question

do not understand what is meant by 10x or how to solve problems involving such factors. Please solve and show a detailed explanation explaining this. 1 L of a 10x western solution has 144g of glycine MW=75g/mol. What is the molarity of glycine if there is only 500ml of this solution available

Answer 1

mass = 144 g

molar mass = 75 g / mol

moles = mass / molar mass

            = 144 / 75

           = 1.92

volume = 500 mL = 0.50 L

molarity = moles / volume

molarity = 1.92 / 0.50

molarity = 3.84 M ---------------------------------> answer

note : here 10x western solution is one solution name thats it . in that 10x western there is glycine is present . we need to calculate glycine molarity in that solution that is the problem
