A solute with a density of 1.15 g/mL and mass of 45.95 g is dissolved in 250. mL of water. What is the volume of the solute and what is the volume percent (v/v)?
• 40.0 mL, 16.0%
• 40.0 mL, 13.8%
• 49.95 mL, 20.0%
• 57.4 mL, 23.0%
To find the volume of the solute, we can use the formula:
Volume (V) = Mass (m) / Density (d)
V = 45.95 g / 1.15 g/mL
V = 39.96 mL
The volume of the solute is approximately 40.0 mL.
To find the volume percent (v/v), we can use the formula:
Volume Percent (v/v) = (Volume of Solute / Total Volume) x 100
V/V = (40 mL / 250 mL) x 100
V/V = 0.16 x 100
V/V = 16.0%
Therefore, the correct answer is 40.0 mL, 16.0%.
To find the volume of the solute, we can use the formula:
Volume of solute = Mass of solute / Density of solute
Given:
- Density of solute = 1.15 g/mL
- Mass of solute = 45.95 g
Volume of solute = 45.95 g / 1.15 g/mL
Volume of solute = 39.96 mL
To find the volume percent (v/v), we can use the formula:
Volume percent (v/v) = (Volume of solute / Total volume) * 100
Given:
- Volume of solute = 39.96 mL
- Total volume = 250 mL (water) + 39.96 mL (solute)
Total volume = 289.96 mL
Volume percent (v/v) = (39.96 mL / 289.96 mL) * 100
Volume percent (v/v) ≈ 13.8%
Therefore, the correct answer is:
• 40.0 mL, 13.8%
To find the volume of the solute, we need to use the formula:
Volume = Mass / Density
Given that the mass of the solute is 45.95 g and the density is 1.15 g/mL, we can calculate the volume as follows:
Volume = 45.95 g / 1.15 g/mL
Volume = 39.96 mL
Therefore, the volume of the solute is approximately 40.0 mL.
To find the volume percent (v/v), we need to divide the volume of the solute by the total volume of the solution (which is the sum of the volume of the solute and the volume of water), and then multiply by 100%.
Given that the volume of the solute is 40.0 mL and the volume of water is 250.0 mL, we can calculate the volume percent (v/v) as follows:
Volume percent (v/v) = (Volume of solute / Total volume) x 100%
Volume percent (v/v) = (40.0 mL / (40.0 mL + 250.0 mL)) x 100%
Volume percent (v/v) = (40.0 mL / 290.0 mL) x 100%
Volume percent (v/v) = 13.79%
Therefore, the volume percent (v/v) is approximately 13.8%.
Hence, the correct option is:
• 40.0 mL, 13.8%
