What is the mass of 65.0mL of ethanol? the density of ethanol at room temperature=0.789g/mL

mass = volume x density

would you multiply 0.789 x 65.0?

yes

the answer that I got once I multiply it is 51.3

The answer is 51.3 grams. Some teachers will count the answer wrong if you don't put the unit (grams in this case) or simply write 65.3 g.

To find the mass of 65.0 mL of ethanol, we need to use the density of ethanol at room temperature, which is 0.789 g/mL.

The formula to calculate mass is:

Mass = Density x Volume

In this case, the volume is given as 65.0 mL, and the density is 0.789 g/mL.

So, we can substitute these values into the formula:

Mass = 0.789 g/mL x 65.0 mL

Now, multiply the density by the volume to get the mass:

Mass = 0.789 g/mL x 65.0 mL = 51.285 g

Therefore, the mass of 65.0 mL of ethanol is 51.285 grams.
