A chemistry student needs 50.0 g of methyl acetate for an experiment. By consulting the CRC Handbook of Chemistry and Physics, t
slamgirl [31]

Explanation:

As density is defined as the mass of a substance divided by its volume.

Mathematically,         Density = \frac{mass}{volume}

It is given that mass is 50 g and density is 0.934 g/cm^{3}.

Hence, calculate the volume of methyl acetate as follows.

                     Density = \frac{mass}{volume}

             0.934 g/cm^{3} = \frac{50 g}{volume}

                       Volume = 53.53 cm^{3}

or,                                  = 53.53 ml                (as 1 cm^{3} = 1 mL)

Thus, we can conclude that the volume of methyl acetate the student should pour out is 53.53 ml.
