A sample of argon, Ar, has a volume of 5.40 L with an unknown pressure. The gas has a volume of 9.73 L when the pressure is 3.62 atm, with no change in temperature and amount of gas. What was the initial pressue in atm of the gas?
O a. 6.523 atm
O b. 6.52 atm
Oc 2.009 atm
Od. 2,01 atm

Explanation:

The initial pressure can be found by using the formula for Boyle's law which is

Since we are finding the initial pressure

From the question we have

We have the final answer as

Hope this helps you

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
