You are trying to determine the density of a piece of metal. You use a balance and find that the mass of the piece of metal is 56.72 g. To determine the volume of the metal, you fill a graduated cylinder to 31.0 mL and then drop the piece of metal into the graduated cylinder. The final volume is 38.9 mL. What is the density of the piece of metal?
To identify the substance, a chemist determined its density. By pouring a sample of the liquid into a graduated cylinder, she found that the volume was 35.1 mL. She also found that the sample weighed 30.5 g. What was the density of the liquid? What was the substance?
Suppose you are trying to find the volume of a box based on the given measurements for the length, width, and height of
the box, where the height was measured in two parts.
length, I = 2.20 in
width, w = 3.11 in
height, h = 10.4 in + 1 in
Calculate the height, h, of the box, first keeping all digits, then rounding to the proper number of significant figures.
unrounded h =
in
rounded h =
in
Calculate the volume (V) of the box using V =Ixw x h. Round to the proper number of significant figures.
V =
in
