20 L of an Ideal Nitrogen Gas (N₂) Are at 0.00°C

question 47

Short Answer

2.0 L of an ideal nitrogen gas (N₂) are at 0.00°C and 1.0 atm. The ideal gas constant is R = 8.314 J/mol · K = 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?
