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
