Question

2. Calculate the mass of solvent in grams in a solution containing 3.0 grams of Tylenol

if the mass percent is 3.5%.

Answer 1

• 83g

Step-by-step explanation:

1, Formula

• Mass percent = (mass of solute/mass of solution) × 100

2. Determine mass of solution

Substitute the data and clear the mass of solution:

• 3.5 = (3.0g / mass of solution) × 100

• 0.035 = 3.0g / mass of solution

• mass of solution = 3.0 g / 0.035

• mass of solution = 85.714g

3. Determine the mass of solvent:

• mass of solvent = mass of solution - mass of solute

• mass of solvent = 85.714g - 3.0g = 82.714g

Round to two significant figures: 83 g
