On a warm summer day in Helsinki, the temperature is 20°C and the relative humidity is 40%. What is the absolute humidity? Numbe
arsen [322]

Answer:

For the resolution of these questions, it necessary to get the information from the well known humidity charts that allow us to accurately and quickly know all the values required for being able to use these values in other more specific procedures, then the values obtained are getting as:

absolute humidity = 0.0069 kg/kg air

humid volume = 128.7 m3 /kg dry air

specific enthalpy = 36.64 kJ/kg

anzhelika [568]

The given question is incomplete, the complete question is:

A reaction between liquid reactants takes place at 10.0 °c in a sealed, evacuated vessel with a measured volume of 35.0 L. Measurements show that the reaction produced 28. g of dinitrogen difluoride gas. Calculate the pressure of dinitrogen difluoride gas in the reaction vessel after the reaction. You may ignore the volume of the liquid reactants. Round your answer to 2 significant digits. pressure:atm

Answer:

The correct answer is 0.28 atm.

Explanation:

The temperature mentioned in the given reaction is 10 degree C, which after conversion becomes 283 Kelvin (273+10 = 283K).  

The volume mentioned in the reaction is 35 Liters.  

The reaction produced 28 grams of dinitrogen difluoride gas (N2F2). The n or the no of moles of the gas can be determined with the help of the formula:  

moles of N2F2 = mass/molar mass

= 28/66 (molar mass of N2F2 is 66 g/mol)

= 0.424

The pressure of the gas can be determined by using the equation of the ideal gas law, that is, PV = nRT

P * 35 = 0.424 * 0.0821 * 283

P = 0.28 atm
