gold had a density of 19.3g/cm3. Silver has a density of 10.5g/cm3. An artist makes a statue out of silver that has a mass of 3.15 kg. what would be the mass of the same statue if it were made out of gold?

Question

anonymous · Answer

hodw do i get the mass?

anonymous · Answer

The mass of silver is given in your problem, however it is in kilograms. Convert it to grams to use densities that are in g/cm^3

anonymous · Answer

i dont understand..

anonymous · Answer

volume required wii be same whether u use gpld or silver....so first find out volume of silver by  mass (in grams)/density.........then multipy that volume by density of gold to find out the mass of gold requred...

anonymous · Answer

Sorry, I screwed up when I was trying to help you.
As Pallavi says: Use 
Density = Mass/Volume
to find the volume of silver. Then use that same equation again, with the volume and density of gold, to find the mass of gold.

its okay ten.....happens..

mathmate · Answer

Wouldn't it be simpler to use proportions, since it is a math problem and not a physics problem?
$$Mass\ of\ gold \ = \ 3.15 \ \times \ \frac{19.3}{10.5}$$

anonymous · Answer

we r doing the same thing above......i tried to explain why we taking proportions u above mentioned....

mathmate · Answer

@pallavi06 The problem can be solved using proportions without the notion of units conversion and densities, which appear to be new math/physics notions to the OP.  

I am sorry to have butted in your conversation, and apologize profusely and sincerely.

hey mathmate....its an open discussion......no need to say sorry.....its always great to know different methodologies to solve same problem......
