what is the mass, in grams, of a pure gold cube that has a volume of 4.50 cm^3(cubed)
i know that gold is 19.3 and the volume is 4.50 but how do i solve this by using density= mass/ volume
please help,
thank you :)
Density = Mass / Volume cross multiply
Mass =Volume x Density
Mass = 4.50 x 19.3 =86.85 grams.
+36916 IF you use the units, you can easily figure this out (as well as other , more comlicated equations)
density = 19.3 gm /cm^3 if you multiply this by volume 4.5 cm^3 the 'cm^3' cancels out and you are left with only grams as units
19.3 gm/ cm^3 * 4.5 cm^3 = 86.85 gm
