1) Roseanne and D'Asia were asked to design and create a paper airplane that would stay in the
air for as long as possible. They began by folding printer paper into four different planes. They
then tested the flying times of the planes by throwing them and timing their flights with a
stopwatch. They compared results and selected the plane with the longest time as their best
design
Which is their independent variable?
A) the time the planes stayed in the air
C) the type of paper used
B) the design of the plane
D) the number of times they threw

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
