Transcript text: At $84.9^{\circ} \mathrm{C}$ and 718 torr, calculate the number of moles and mass of 7.30 L of $\mathrm{N}_{2}$ gas. Round your answer to 3 significant figures.
Solution
Solution Steps
Step 1: Convert temperature to Kelvin
Para usar la ecuación de los gases ideales, primero convertimos la temperatura de grados Celsius a Kelvin.
\[
T(K) = 84.9 + 273.15 = 358.05 \, \text{K}
\]
Step 2: Convert pressure to atmospheres
Convertimos la presión de torr a atmósferas usando el factor de conversión \(1 \, \text{atm} = 760 \, \text{torr}\).
