Curious Carl's chemistry teacher asked him to make a sugar solution. Carl dissolved 50.0 grams of sucrose (C12H22O11, molar mass 342.3 g/mol) in 1.00 L of water. If molarity = moles/liter, what is the molarity of Carl's sugar solution?
A)0.008m
B)0.146m
C)0.190m
D)0.342m

Answer 2

Answer:The correct answer is option B.

Explanation:

Mass of surcose dissolved = 50.0 g

volume of water = 1 L

Molarity=$\frac{\text{Mass of sucrose}}{\text{molar mass of sucrose}\times \text{volume of solvent in L}}$

$Molarity=\frac{50.0 g}{342.3 g/mol\times 1 L}=0.1460 mol/L$

Hence ,the correct answer is option B.
