Calculate the density of a coin with a mass of 11.34 grams, a diameter of 30.61 mm and a thickness of 2.15 mm. Express the answer in grams/cubic centimeters using 3 significant numbers
Homework Answers
Density= mass/volume
Here mass = 11.34 gm
Volume= (pi) r^2*h
r= radius= 15.31 mm= 1.53 cm , h= 0.21 cm
Plugging the values of r and h , volume = 1.54 m^3
Density= 11.34/1.54 gm/cm^3= 7.36 gm/cm^3
