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.

mass = volume x density
