20 POINTS!! 1. 14.07g of solid sucrose (C12H22O11) are dissolved in 0.35 L of water. What is the molarity of the solution?

2. What is the molarity of a sucrose solution with a concentration of 4.5 ppm (mg/L)?

3. What is the molarity of the same sucrose solution if you dilute 40 mL of it into a 500 mL volumetric flask?

1. molarity is = 0.1174

2. molarity is = 9.3

3. molarity is =0.009392

Explanation:

Q#1.

mass of sucrose is 14.07g

molar mass of sucrose is 342 3g/mol

so, 14.07x1/342.3 = 0.0411

now the volume is of water is 0.35

so, 0.0411/0.35 = 0.1174

Q#2.

concentration is 4.5

so, 4.5x1/1000= 0.0045

then, 0.0411/0.0045 = 9.13

Q#3.

M1M1=M2M2

molarity of the same sucrose is 0.1174

so, diluted in 40mL

and the volumetric flask is 500mL

so, 0.1174x40/500= 0.009392
