Question

If the density of ethanol is 0.789 g/mL, how many milliliters are produced in this reaction?

Answer 1

The volume of the ethanol is 6.7 mL

What is the density of the ethanol?

We know that density is defined as the ratio of the mass to the volume of an object. We know that the density is said to be an intrinsic property and this means that we can use the density of the object to be able to obtain the kind of object that we are dealing with.

We have the information that the mass of the carbon dioxide that can be obtained from the reaction is about 10 g. We can now use this to obtain the number of moles by the use of the formula;

Number of moles = mass/ molar mass

= 10 g/44 g/mol

= 0.23 moles

From the reaction equation:

1 mole of ethanol produces 2 moles of carbon dioxide

x moles of ethanol produces 0.23 moles of carbon dioxide

x = 0.23 × 1 /2

= 0.115 moles

Mass of ethanol = 0.115 moles × 46 g/mol

= 5.29 g

Volume of the ethanol = mass/density

volume = 5.29 g/0.789 g/mL

= 6.7 mL
