Suppose you have 150. ml of a substance with density of 28.0 g/dm3. convert the volume from milliliters to liters to cubic decimeters, then determine the mass of the sample in grams. also show the unit analysis by dragging components into the unit-factor slots below. the question marks (?) represent the answer to the previous step.

1 ml = 1 cm³

1 dm = 10 cm

1 dm³ = 10³ cm³

150. ml = 150. cm³

150. cm³ * 1 dm³ / (1000 cm³) = 0.150 dm³

or

1 ml = 1 cm³ * 1m³ / (10²) ³ cm³=1 / (10⁶) m³ * (10 dm) ³/1m³ = 10⁻³ dm³

150. cm³ * 10⁻³ dm³ / 1 cm³ = 0.150 dm³

0.150 dm³ * 28.0 g/dm³ = 4.20 g
