Density is given by the equation D=m/V, were D is density, m is mass in grams, and V is volume in cubic centimeters.
In this problem, we have density and we have mass so we can plug into the equation and solve for V.
38.6=270.2/V
<em>*Multiply both sides by V*</em>
38.6V=270.2
<em>*Divide both sides by 38.6*</em>
V=7
The volume of the gold nugget is 7cm3.

Hello there!
In this case, according to the given information, it possible for us to realize that this problem is solved via the ideal gas equation:
By which we solve for n (moles) as shown below:
Then, we plug in the given pressure, volume and temperature (in K) to obtain:

A scientist would measure the amount of carbon-14 (¹⁴C) in a fossil to determine its age.
The ¹⁴C:¹²C ratio is constant in living organisms. When they die, the radioactive ¹⁴C decays, so the ratio changes. The half-life for the for the decay is 5730 a, so scientists can work backwards and calculate how long ago the plant died. The method is good for determining the age of fossils up to 50 000 a old.
