± Molarity A solution is a homogeneous mixture of two or more substances. In a solution, the component present in a smaller proportion is called the solute while the component present in larger proportion is called the solvent. Water is an exception. It is always conskdered the solvent regardless of the amount The concentration of a solution is the amount of solute dissolved in a given amount of solution: amount ot solute amount of solution concentration The concentration of a solution can be expressed in many different ways. One of the most commonly used units of concentration in chemistry is molity (M, or molar concentration, which is the number of moles of solute in 1 liter (L) of solution Molarity is defined by the equation molarity- mber of males of nolute liters of A solution of sucrose that has a concentration of 1 mol of sucrose per liter of solution contains 342 g of sucrose, which equals 6.023 x 1023 molecules of sucrose.

part A
Molarity(M) = no of moles of solute present in one litre of solution.
molarity of sucrose = 0.5/2 = 0.25 M (lowest molarity)
molarity of glucose = 0.5/1 = 0.5 M
molarity of NaOH = 0.75/1 = 0.75 M (highest molarity)
molarity of table sat = 1/2 = 0.5 M
part B
Molarity = n/V
0.5 = n/2.5
n = no of mol of sucrose = 1.25 mol
part C
Molarity = (w/mwt)*(1/V)
= (171/342)*(1/1.25)
= 0.4 M
