A sample of nitrogen gas collected at a pressure of 1.03 atm and a temperature of 279 K is found to occupy a volume of 568 milliliters. How many moles of N2 gas are in the sample

0.025 moles of nitrogen gas are there in the sample.

Explanation:

According to ideal gas equation:

P = pressure of gas = 1.03 atm

V = Volume of gas = 568 ml = 0.568 L   (1L=1000ml)

n = number of moles  = ?

R = gas constant =

T =temperature =

0.025 moles of nitrogen gas are there in the sample.

"the periodic table is arranged in order of atomic number."

im not exactly sure but i think its b!
