Density is defined as the mass per volume. In problems 1, 2, and 4, you will be dividing the mass by the volume to determine density. Problem 3 asks for weight, so you will be multiplying volume by density to determine mass.

#1

40.5 g / 15 ml = 2.7 g/ml

#2

306.0 g / 22.5 ml = 13.6 g/ml

#3

0.789 g/ml * 200 ml = 157.8 g

#4

1896 g / 212.52 ml = 8.92 g/ml

(Since 1 cubic cm = 1 ml, we can find the volume by multiplying the lengths of the block's sides: 8.4 cm * 5.5 cm * 4.6 cm = 212.52 cm^3 = 212.52 ml)

all but the second one

step-by-step explanation:

cuz that one goes over 180

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
