I am having to find the density of 1 oz of gold with the width being 1.47 cm. , height 2 cm, and .5 cm thick. I know that density is mass/volume but I have to convert to the metric system. What would be the density of this gold bar, using the metric system? I would like to see this problem worked out so I can apply it to my other questions.
Remember that for volumes; 1mL= 1cm x 1cm x 1cm= 1cm(cubed)= 1 cc.
1 oz= 28.35 grams

Density of Planets and Moons Lab Objectives: In this lab you will learn: Part 1 – What density is, and how to experimentally determine it Part 2 – To calculate various physical quantities for the planet Mercury Part 3 – Group major solar system bodies by density Part 1. DENSITY Definition – Density =mass / volume. Symbolically, we write this as , where 1) ρ (the Greek letter “rho”) is the density, 2) m is mass, and 3) V is...
