question 4

Multiple Choice

A sealed container holds 0.020 moles of ideal nitrogen $\left( \mathrm { N } _ { 2 } \right)$ gas, at a pressure of 1.5 atm and a temperature of 290 K. The atomic mass of nitrogen is 14.0 g/mol. How many molecules of nitrogen are in the container? $( R = 8.31 \mathrm {~J} / \mathrm { mol } \cdot \mathrm { K } , 1 \mathrm {~atm} = 101 \mathrm { kPa } )$

• A) \(6.0 \times 10 ^ { 21 } \mathrm {~mol}\)
• B) \(2.4 \times 10^{22} \mathrm {~mol}\)
• C) \(1.2 \times 10 ^ { 22 } \mathrm {~mol}\)
• D) \(3.0 \times 10 ^ { 21 } \mathrm {~mol}\)
• E) \(1.5 \times 10^{21} \mathrm {~mol}\)
