What is the mass (in grams) of 500 mL of ethanol? (density of ethanol = 0.789 g/mL)
- A. 394.5 mL
- B. 500 mL
- C. 394.5 g
- D. 500 g
Correct Answer: C. 394.5 g
Explanation
To calculate the mass of a substance, we can use the formula: Mass = Volume x Density Given the volume of ethanol is 500 mL and the density of ethanol is 0.789 g/mL, we can plug the values into the formula: Mass = 500 mL x 0.789 g/mL = 394.5 g
