katovenus [111]

Answer:

Mass of 205 mL of the liquid is 164 g

We know, $density=\frac{mass}{volume}$

Here density of liquid is 0.798 g/mL and volume of liquid is 205 mL

So, mass of liquid = $density\times volume$

= $(0.798 g/mL)\times (205 mL)$

= 164 g

hence mass of 205 mL of the liquid is 164 g.
