You find an old gold ring in your house. You are sure it is gold but you do not know what
karat it is. After chemistry class you determine the mass and volume of the ring. You
determine its mass is 14.3 g and its volume is 0.808 g. Next calculate the density of the ring and determine what karat gold it is.
Can someone me with this question plz
