A student needs 15.0 g of ethyl alcohol for an experiment. If the density of the alcohol is

0.789 g/mL, how many milliliters of alcohol are needed?

Respuesta :

V = 15.0 / 0.789 g/mL = 19.0 mL i believe this is correct

Answer:

19.011 mL

Explanation:

Upon bringing out the parameters mentioned in the question we have;

Mass = 15.0g

Density = 0.789 g/mL

Volume (mL) = ?

The relationship between all three parameters is given as;

Density = Mass / Volume

0.789 = 15 / V

V = 15 / 0.789 = 19.011 mL
