Homework Statement
Mass of copper = 321.5 g
Volume = 36 cm3
What is the density?
How many significant figures should you give your density? Explain.
Homework Equations
The Attempt at a Solution
The BOOK says two significant figures = 8.9 g/cm3 "since the volume is given to only two significant figures".YES the volume is to two significant figures but the mass of copper 321.5 g is to four significant figures.
The full value for density of copper is 8.9305 which is five significant figures. So why did the book decide that 2 significant figures is appropriate (8.9) and not four significant figures (8.930)?
