An ideal gas has a temperature of 25 oC, a pressure of 1.7 atm, and volume of 345 mL, how many moles of gas are present in the container?

There are 0.024 moles of gas are present in the container.

Explanation:

Given: Temperature = = (25 + 273) K = 298 K

Pressure = 1.7 atm

Volume = 345 mL (1 mL = 0.001 L) = 0.345 L

Formula used is as follows.

PV = nRT

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T= temperature

Substitute the values into above formula as follows.

Thus, we can conclude that there are 0.024 moles of gas are present in the container.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
