Homework Help: Chemistry

Posted by Connie on Tuesday, October 11, 2011 at 6:34pm.

The density of any material can be determined by the slope of a straight line by plotting mass values and vol. values M=DV
Mass g. Vol.ml
#1 0.55 0.60
#2 1.75 1.80
#3 3.50 3.40
#4 5.60 5.25
#5 7.50 7.00

I need to find the slope and graph the info.
So do I make the graph with Y (Vert.) axis being Mass and Vol=x axis and plot points???

Then to Find the slope I am stuck
.60-0.55=
1.80-1.75=
3.40-3.50=

The only answer choices for slope are
1.094, 0.914 and 1.024 but I can't even get one of those choices.
Please Help Thank you!
