How many moles of O2 gas are there in a 1.0 L container which contains 0.12 atm of O2 gas at 25 ºC? (The correctly abbreviated unit in the correct case is required for this question.)

The number of moles of oxygen gas in the container is 0.0049 moles

Explanation:

To calculate the moles of oxygen gas, we use the equation given by ideal gas which follows:

where,

P = pressure of the gas = 0.12 atm

V = Volume of the gas = 1.0 L

T = Temperature of the gas =

R = Gas constant =

n = number of moles of oxygen gas = ?

Putting values in above equation, we get:

Hence, the number of moles of oxygen gas in the container is 0.0049 moles

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
