Question

You and your friend have found a piece of gold in your backyard, but you want to make sure it's actually real gold before you take it to the bank. You know the bar has a mass of 30 grams and a volume of 2 cm3. Calculate the density of the piece of gold. Then determine if the piece of gold can be real? Why or why not? (HINT: The density of real gold is 19.32 g/cm3).

Answer 1

Answer:

$</p><p>density = \frac{mass}{volume}\\ \\ \\</p><p>= \frac{30}{2} = 15g/cm^3\\ \\ \\</p><p>therefore\: it \: is \: not \: real\: gold\: because\: it's\\ \\ \\ \: density\: is \: lesser\: than \: density \: of \:\\ \\ \\ real \: gold.$

Answer 2

Answer:

density = mass/ volume

30÷2=15g/cm3

therefore it is not real gold because it's density is less than real gold
