Final answer:
The mass of helium can be calculated using the ideal gas law after converting given units to standard ones, and the pressure, temperature, and volume are interrelated properties critical for the accuracy of calculations in practical applications.
Step-by-step explanation:
To calculate the mass of helium using the ideal gas law, PV = nRT where P is pressure, V is volume, n is moles of the gas, R is the ideal gas constant, and T is temperature in Kelvin. First, we need to convert the temperature from °C to K by adding 273.15, and pressure from psi to atm (1 psi = 0.068046 atm).
Then we find the number of moles (n) using the ideal gas equation and finally, calculate the mass using the molar mass of helium (4.002602 g/mol).
Pressure (P) affects the volume and temperature of a gas, whereas the volume (V) also influences the temperature and pressure. Temperature (T) impacts the kinetic energy of gas molecules affecting both volume and pressure.
All three properties are interconnected and adjusting one will affect the others according to the ideal gas law.
In the context of calculating the mass of helium, measuring conditions are crucial. They ensure that the calculations are accurate and reflect real-world scenarios, considering that actual gas behavior deviates from the ideal under extreme conditions.
The given parameters in gas calculations are significant to ensure precise and applicable results in practices such as ballooning or scientific measurements.
