The answer is 2.78 moles of Si
Answer:
1.2 atm
Explanation:
Given data
- Volume of the gas in the tank (V₁): 200.0 L
- Pressure of ethylene gas in the tank (P₁): ?
- Volume of the gas in the torch (V₂): 300 L
- Pressure of the gas in the torch (P₂): 0.8 atm
If we consider ethylene gas to be an ideal gas, we can find the pressure of ethylene gas in the tank using Boyle's law.
Atomic mass unit is the standard unit that is used for indicating mass on an atomic or molecular scale
Speed of light is 3.0*10^8
frequency = wavelength / speed
= 1400 Hz
