How many moles of oxygen must be in a 10.0 L container to exert a pressure of
0.844 atm at a temperature of 25.0 °C?*

0.345 mol

Explanation:

We can solve this problem by using the equation of state for an ideal gas, which is

where

p is the pressure of the gas

V is its volume

n is the number of moles

R is the gas constant

T is the absolute temperature of the gas

For the oxygen in this problem we have:

V = 10.0 L is the volume

p = 0.844 atm is the pressure

is the gas constant

is the absolute temperature of the gas

Solving for n, we find the number of moles:

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

hope this and sorry i could only come up with one answer!
