The moon’s average density is about 3.34 grams per cubic centimeter. what is this density in units of pounds per cubic inch?

As per the question the average density of the moon [ω]

The density of a substance is defined as mass per unit volume.Mathematically density ω =

                                                    We are asked to convert this value from to

We know that one gram is equal to .0022 pound i.e

                                      1 gram=.0022 lb

Again one centimetre is equal to .394 inch i.e

                                     1 cm=.394 inch

      Hence density[ ω]= 3.34  

                            ⇒ω

                            ⇒ω

                            ⇒ω    [ans]

a.) travels faster in solids because the particles are closer together.
