Question

A scientist stores a very large number of particles in a container in order to determine the number of particles the scientist measures the temperature, pressure, and volume of the container and calculate the moles using the ideal gas law in order for the calculated value to have the greatest accuracy the scientist shoulld make sure that:_______.

Answer 1

To keep the variables of pressure, temperature and volume constant in the process

Step-by-step explanation:

For a confined gas, Avogadro’s law states that the volume (V) is directly proportional to the number of moles (n) if both the temperature and pressure values remain constant.

Mathematically this can be expressed as:

​V∝n

​​ or V=k×n where k, is the constant of proportionality

​

​or

​​

​n1/V​1​​ = n2/V2

​​

Similar Mathematical relationships can be made for the other pairs of variable of Pressure versus n, and Temperature versus n.

Answer 2

Answer: the scientist should ensure that the volume is measured in dm3(or L), the pressure in atm, the temperature in Kelvin and use the gas constant 0.082atm.dm3.K^-1.mol^-1
