Suppose you have 150. ml of a substance with density of 42.0 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.

First let's make the conversions corresponding to the volume:
 milliliters to liters:
 150 (ml) * (1/1000) (L / mL) = 0.15 L
 Liters to cubic decimeters
 0.15L * (1/1) (dm ^ 3 / L) = 0.15 dm ^ 3
 Then, by definition, density is equal to mass between volumes:
 d = m / v
 Clearing the mass we have:
 m = d * v
 Substituting:
 m = (42.0 g / dm3) * (0.15 dm ^ 3)
 m = 6.3g
 
 the mass of the sample in grams is
 m = 6.3g

This is what i found on google “kinetic energy. energy is transferred from one object to another when a reaction takes place. energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few. this energy would be in the form of motion, with the person lifting the blue ball to a higher level.” i hope this you
