If an irregularly shaped apple possesses a density of 0.96 g/cm 3 , what is its mass in milligrams? (The volume of the given cylinders are in mL).

In this practice question it says, If an irregularly shaped apple possesses a density of 0.96 grams per centimeters cubed, what is its mass in milligrams? Here we're given the information that the volume of the given cylinders are in milliliters. Alright. So we're going to start out with the fact that we have 5 ml's to begin with. And after we've added the irregular shaped apple the volume is now 10 ml's. This is enough information by water displacement to know that the volume of the apple is 10 ml's minus 5 ml's. So it's 5 ml's for the volume of the apple. I'm going to use this piece of information now to help me determine the mass of the apple. So we have 5 ml's and remember that ml's in density, ml's in centimeters cubed actually are the same thing in terms of conversion factors. So we're gonna say 1 ml is the same thing as 1 centimeters cubed. And that's important because the density uses centimeters cubed. We want to cancel out the centimeters cubed, so we put them on the bottom. So 1 centimeters cubed, and up top we're gonna put 0.96 grams. Centimeters cubes have cancelled out and now we want milligrams at the end. So we have to do one more conversion. So So here we're going to say that 1 milli is 10 to the negative 3. So here at the end we're going to get milligrams, which would give us an answer of 4,800 milligrams. Here 4,800 milligrams has 2 sig figs in it, which is good because 0.96 also has 2 significant figures. So this would be our final answer.
