Please help with these two questions

In a laboratory experiment a gas is collected in an inverted tube and connected to a manometer. If the surface (i.e., H) of the liquid exposed to the gas in the inverted tube is 0.15 m higher than the liquid surface exposed to the atmosphere with pressure Pa then what is the pressure Po of the gas (in atm) in the tube. The density of the liquid is 1.23 g cm-3, and the atmospheric pressure is 790 mmHg, = S To solve this problem fist calculate the pressure at the bottom of the column which is density of liquid x height of column of liquid x gravitational acceleration (i.e., P = p*h*g). Watch your units. 1 Pa = 1 kg s-2 m-1; 1 atm 101,325 Pa. 1.057 atm Submit Answer Incorrect. Tries 4/10 Previous Tries Based on planetary data scientists have discovered a new planet several light years away from earth. Based on their measurements they estimate the mass of planet's atmosphere to be 2.27x1019 kg. Given that the surface area of the planet is 3.39x1015 m2 and the acceleration due to gravity is 1.65 m s-2 estimate the atmospheric pressure in kPa of the new planet. 111 kPa Submit Answer Incorrect.
