Answer: The volume of 0.05 moles of Ncon gas at STP is 1.19 liters (L).
Step-by-step explanation:
At STP (Standard Temperature and Pressure), the temperature is 273.15 K (0°C) and the pressure is 1 atmosphere (atm).To find the volume of 0.05 moles of Ncon gas at STP, we can use the ideal gas law:PV = nRTwhere P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.At STP, the pressure is 1 atm, and the temperature is 273.15 K. The gas constant R is 0.08206 L⋅atm/(mol⋅K).Substituting these values into the ideal gas law and solving for V, we get:V = nRT/P
V = (0.05 mol) x (0.08206 L⋅atm/(mol⋅K)) x (273.15 K) / (1 atm)
V = 1.19 L Therefore, the volume of 0.05 moles of Ncon gas at STP is 1.19 liters (L).
