Explanation:

Given parameters:

Density of the ethanol  = 0.789g/mL

Volume of the ethanol in the cylinder = 900mL

Unknown:

Mass of the ethanol  = ?

Solution:

Since density is the mass per unit volume of a substance;

      mass  = density x volume

Now insert the parameters and solve;

   mass  = 0.789g/mL x 900mL

   mass  = 710g

In scientific notation we have 7.10 x 10²g

What is the difference between the atomic number and the mass number of an element?
DedPeter [7]

Mass number is the number of protons and neutrons in an atom, and it tells us about the mass of the atom in amu, or atomic mass units. Atomic mass is the average mass of all the isotopes of a certain type. It is a weighted average that takes into account the abundances of all of the different isotopes

hope this helps :)
