Question

Limestone and quartz are common minerals found in Florida. Sarah has a piece of each, but does not know which is which. To find out, she plans an investigation to determine the density of each sample, because limestone has a lower density than quartz. Density is equal to the mass divided by volume. She places a piece of each mineral into a graduated cylinder that contains water. The table shows the measurements Sarah recorded. What can Sarah most likely conclude is true? Mass of Mineral 1 9.50g Mass of Mineral 2 9g Volume of water in graduated cylinder 25ml Volume of water and mineral 1 in graduated cylinder 30ml Volume of water and mineral 2 in graduated cylinder 28.4 ml *

a.) Mineral 2 is limestone because it has less mass
b.) MIneral 1 is limestone because it has more mass
c.) MIneral 1 is limestone because it has a lower density
d.) Mineral 2 is limestone because it has a lower density

Answer 1

Answer: c.) Mineral 1 is limestone because it has a lower density

Step-by-step explanation:

Given data:

Mass of Mineral 1 = 9.50g

Mass of mineral 2 = 9g

Volume of water in graduated cylinder = 25ml

Volume of water displaced by mineral 1 = 30ml

Volume of water displaced by miners 2 = 28.4ml

Therefore;

Density of mineral 1

= 9.50g / 30ml

= 0.3167 kg/m^3

Density of mineral 2

= 9g / 28.4

= 0.3169 kg/m^3

Therefore Mineral 1 is limestone because due to it’s lower density.
