Alvaro Price · Answer 1

The student has to weigh 7.9 ±0.1 grams

Explanation:

Density of acetone : 0.790 g/cm³

If the student has to measure 10.0 mL of acetone, he can weigh an specific mass.

Density of acetone = Mass of acetone / Volume of acetone

cm³ = mL

0.790 g/cm³ = Mass of acetone / 10 cm³

0.790 g/cm³. 10cm³ = 7.9 g
