Asample of 88.0 g co2 is held at 291 k in a 40.0 l container. what is the pressure this gas exerts on the container. express your answer in kpa.

- 121 kPa.

Solution:- mass, temperature and volume are given for carbon dioxide gas asked to calculate the pressure this gas exerts on the container.

It is based on ideal gas law equation, PV = nRT .

Where, P is the pressure in atm, V is the volume in Liters, n is the number of moles of the gas, R is the universal gas constant and it's value is and T is the kelvin temperature.

Given data:- mass = 88.0 g

T = 291 K

V = 40.0 L

P = ?

We need to convert the mass to moles and for this we divide the mass by molar mass. Molar mass of carbon dioxide gas is 44.01 gram per mol.

n = 2.00 mol

The equation could be rearranged for pressure as:

Let's plug in the values and solve this for P.

P = 1.1946 atm

Since the answer is asked to report in kPa, let's convert atm to kPa.

1 atm = 101.325 kPa

So,

= 121 kPa

So, the pressure this gas exerts on the container is 121 kPa.

lol idk man i guess u gotta ask bill nye the science guy

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
