Question

The pressure caused by a sample of gas is 2.25 atm. 1 atm is

equal to 1.01 kPa. What is the pressure in Newton per square
centimeter?

Answer 1

`0.326(N)/(cm^2)`

Step-by-step explanation:

Hello.

In this case, considering that 1 atm equals 1.01 kPa, we can compute the pressure in kPa first as shown below:

`2.25atm*(1.01kPa)/(1atm) =3.26kPa`

Now, we convert kPa to Pa, considering 1 kPa equals 1000 Pa:

`3.26kPa*(1000Pa)/(1kPa)=3260Pa`

Now, since Pa is equal to N/m², and 1 m equals 100 cm, the pressure in newton per square centimeter turns out:

`3260(N)/(m^2)*((1m)/(100cm))^2 \\\\0.326(N)/(cm^2)`

Best regards.
