To calculate the weight of 1 mole of helium (He) gas given its density at NTP (Normal Temperature and Pressure), we can follow these steps: ### Step-by-Step Solution: 1. **Understand NTP Conditions**: - At NTP, the temperature is 273.15 K and the pressure is 1 atm. Under these conditions, the volume of 1 mole of any ideal gas is approximately 22.4 liters. 2. **Given Data**: ...
