Mendeleev arranged the elements according to their atomic masses
Benedict's solution is used to test simple sugars, such as glucose. It is blue solution, when sugar is present, it turns to orange / brick red. Depends on the concentration of sugar.
Answer: Concentration of the chemist's sodium chloride solution is 34.4 mol/L.
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
where,
n= moles of solute
= volume of solution in ml
Given : moles of = 6.89
volume of solution = 200 ml
Putting in the values we get:
Thus the concentration of the chemist's sodium chloride solution is 34.4 mol/L.
