Question

Which solution is the most concentrated? Each choice refers to the same solute and solvent. A) 2.4 g solute in 2 mL solution B) 2.4 g solute in 5 mL solution C) 20 g solute in 50 mL solution D) 30 g solute in 150 mL solution E) 50 g solute in 175 mL solution

Answer 1

A

Step-by-step explanation:

The units for concentration can be g/ml (grams per milliliter)

Hence we will need to calculate the concentration for each option before making a decision:

A = 2.4 / 2 = 1.2 g/ml

B = 2.4 / 5 = 0.48 g/ml

C = 20 / 50 = 0.4 g/ml

D = 30 / 150 = 0.2 g/ml

E = 50 / 175 = 0.286 g/ml

Using these values, the concentration with the highest value will give us the most concentrated solution, which in this case is option A at 1.2 g/ml.
