Answer:
4 × 10⁻³ L
Step-by-step explanation:
Density = 0.875 g/mL
Mass = 3.5 grams
Volume = ?

Density = mass / volume
0.875 = 3.5/Volume
*Cross's multiply*
Volume = 3.5/0.875
Volume = 4 mL
The unit of volume is Litres (L), which means mL must be converted to L
To convert from a prefix to a non-prefix, the prefix notation will be replaced with the numeric equivalent of the prefix in the expression
Milli (m) = 10⁻³
So 10⁻³ will be replaced in the place of m
4 mL = 4 (10⁻³) L
4 × 10⁻³ L
Volume = 4×10⁻³ L
