Ethanol is a common laboratory solvent and has a density of 0.789 g/mL. What is the mass in gram of 123 mL of ethanol?
To find the mass of 123 mL of ethanol, we can use the formula:
Mass = Density × Volume
Given that the density of ethanol is 0.789 g/mL and the volume is 123 mL, we can substitute these values into the formula:
Mass = 0.789 g/mL × 123 mL
Now we can multiply the density and volume:
Mass = 97.047 g
Therefore, the mass of 123 mL of ethanol is 97.047 grams.
