Convert your weight (the force due to gravity) from pounds to Newton's (1 lb = 4.45 N). b) Using the fact that on the surface of the Earth, where g is constant, 1 kg has a weight of 2.2 lbs, find your mass in kg. C) Convert your height in feet and inches into meters (1 ft = 30.48 cm; 1 in = 2.54 cm).
At equilibrium, the pressures of NH3 and HCl are both equal to 0.00552 atm, and the mass of NH4Cl (s) is 35.4 g. Calculate the equilibrium pressure of NH3 after 11.3 g of NH4Cl (s) is added to the container?
