Approx....150*g

Explanation:

Look at the quotient defines density....

"density," rho="Mass of solvent"/"Volume of solvent"...and this units of g*mL^-1 are appropriate....

To get the mass, we take the product....

"Mass of solvent"=rhoxx"volume of solvent"

0.8786*g*cancel(mL^-1)xx175.4*cancel(mL)=??g

If benzene were added to water to form solvent layers, which layer would be on the bottom?

154.10644 g

Explanation:

Using dimensional analysis,
175.4mL(0.8786g/(mL))
=154.10644g

Using the formula for density,
rho=(mass)/(volume)

Rearranging the equation,
mass=rho*volume
mass=0.8786*175.4
mass=154.10644g
