20 L of a Ideal Nitrogen Gas (N₂)are at 0

question 15

Short Answer

2.0 L of a ideal nitrogen gas (N₂)are at 0.00°C and 1.0 atm.The ideal gas constant is = 0.0821 L • atm/mol • K,Avogadro's number is 6.022 × 10²³ molecules/mol,and the ATOMIC mass of nitrogen is 14 g/mol.
(a)Determine the number of moles of N₂.
(b)How many molecules of N₂ are present?
(c)What is the mass of this gas?
