Imagine that the apparent weight of the crown in water is = 4.50n, and the actual weight is = 5.00n. is the crown made of pure (100%) gold?
the density of water is = 1.00 grams per cubic centimeter. the density of gold is = 19.32 grams per cubic centimeter.

Answer : The crown is not made of pure (100%) gold.

Explanation :

Formula used :

where,

= apparent weight of the crown in water = 4.50 N

= actual weight = 5.00 N

= density of water =

= density of crown = ?

Now put all the given values in the above formula, we get:

Density of crown < Density of gold

Thus, the crown is not made of pure (100%) gold.

so what is the problem with your lab report and whats the subject of the lab report? i will you
