Answer:
V2~0.4839M
Explanation:
We're going to use Boyles law to answer the question.
Boyle's law:
P1V1=P2V2
P1=151mmHg
P2=166mmHg
V1=0.532L
V2=?
V2=(P1 x V1)/P2
V2=(151 x 0.532)/166
V2~0.4839M

Answer:
Explanation:
<u>1, Formula</u>
- Mass percent = (mass of solute/mass of solution) × 100
<u>2. Determine mass of solution</u>
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
<u>3. Determine the mass of solvent:</u>
- 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
