The mass of 340mL of ethyl alcohol is 269g.
HOW TO CALCULATE MASS:
- The mass of a substance can be calculated by multiplying the density by its volume as follows:
Mass (g) = Density (g/mL) × volume (mL)
- According to this question, ethyl alcohol is said to have a density of 0.79g/mL and a volume of 340mL, hence, the mass of ethyl alcohol can be calculated as follows:
Mass of ethyl alcohol = 0.79 × 340
Mass of ethyl alcohol = 268.6
Mass of ethyl alcohol = 269g.
- Therefore, the mass of 340mL of ethyl alcohol is 269g.
