What is the mass in grams of 500 mL of ethanol ... - JAMB Chemistry 2023 Question
What is the mass (in grams) of 500 mL of ethanol? (density of ethanol = 0.789 g/mL)
394.5 mL
500 mL
394.5 g
500 g
The correct calculation for the mass of 500 mL of ethanol would be:
\[ \text{Mass} = \text{Volume} \times \text{Density} \]
Given:
- Volume of ethanol = 500 mL
- Density of ethanol = 0.789 g/mL
\[ \text{Mass} = 500 \, \text{mL} \times 0.789 \, \text{g/mL} = 394.5 \, \text{g} \]
To calculate the mass of a substance, you can use the formula: \(\text{Mass} = \text{Volume} \times \text{Density}\). Given the volume of ethanol is 500 mL and the density of ethanol is 0.789 g/mL, you can plug the values into the formula:
\[ \text{Mass} = 500 \, \text{mL} \times 0.789 \, \text{g/mL} = 394.5 \, \text{g} \]
