Calculate the solubility (in M units) of ammonia gas in water at 298 K and a partial pressure of 8.00 bar . The Henry’s law constant for ammonia gas at 298 K is 58.0 M/atmand 1 bar=0.9869 atm. Express your answer in molarity to three significant figures.
At 298 K and 1 bar pressure, the density of water is 0.9970 g⋅cm−3, the coefficient of thermal expansion, is 2.07×10−4 K−1, and CP,m=75.3 J⋅K−1⋅mol−1. Part A: If the temperature of 336 g of water is increased by 27.9 K, calculate w Part B: If the temperature of 336 g of water is increased by 27.9 K, calculate q. Part C: If the temperature of 336 g of water is increased by 27.9 K, calculate ΔH. Part D: If the...
9. The absolute pressure in water at a depth of 5 m is 145 kPa. What is the absolute pressure in a liquid whose specific gravity is 1.34 at the same depth? Hint: Determine the atmaspheric pressure first 10. Water is pumped from a lake to a storage tank 30 m above at a rate of 55 L/s, while consuming 22.6 kW of electrie power to run the motor. Detemine the overall efficiency of the motor-pump unit. .A hydraulic power...

(a) What is the vapor pressure of water at 20.0◦C? (b) What percentage of atmospheric pressure does this correspond to? (c) What percent of 20.0◦C air is water vapor if it has 100% relative humidity? (The density of dry air at 20.0◦C is 1.20 kg/m3). I got that the vapor pressure of the water will be 2.33x103 Pa, but I am getting hung up on the formula for part b, which is where I can really use the extra help...
