Students are comparing mineral samples, and they are stumped. Eli suggested they calculate the density of the mineral since it is a property unique to any pure substance. To calculate density the students had to record two important measurements. First they used the balance to measure the mass of the mineral. What was the purpose of the graduated cylinder?
A) They used water displacement to find the volume of the mineral sample.
B) They used water displacement to calculate the weight of the mineral sample.
C) The students wanted to see if the mineral would float. That helps them figure density.
D) Because they could not measure the sample with a ruler, they had to find the mass using water displacement.
CAN SOMEONE PLEASE HELP ME!!

Aflask with vinegar in it has a mass of 160 grams. a balloon with baking soda in it has a mass of 40 grams. the balloon is attached to the flask to seal the opening and the vinegar and baking soda mixes. the balloon inflates to a large volume. what will the total mass of the balloon and flask be after the balloon inflates? explain. a) less than 200 grams because the solid baking soda disappears. b) 200 grams, because all the atoms remain in the balloon or flask. c) more than 200 grams because the size of the balloon is so much larger. d) less than 200 grams because gases such as the one in the balloon are lighter than solids and liquids.
