The answer is
<h2>4.0 g/cm³</h2>Explanation:
The density of a substance can be found by using the formula
<h3>From the question
mass of block = 36 g
volume = 9 cm³
The density is
We have the final answer as
4.0 g/cm³

Charles law states that volume of gas is directly proportional to temperature at constant pressure
V/T = k
where V - volume , T - temperature and k - constant
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
in the question it states that the temperature has been increased from 278 K to 231 K but it should actually be temperature is decreased from 278 K to 308 K
substituting the values in the equation
V = 462 cm³
the answer should be D. 462 cm³
