A J-shaped tube, closed at one end, is depicted in the figure at the right. It contains N2 gas that is trapped by an unknown liquid whose density is twice as large as that of mercury. The other end of the tube is open to the air. The value of h is measured to be 10 mm at sea level on a clear day at a temperature of 27°C. The atmospheric pressure is 1.00 atm. Assuming the vapor pressure of the liquid is zero, what is the concentration of the N2 gas trapped inside the J-shaped tube?

the amount of concentration is about 23.9 grams of concentration you might want to add some hydrochloric acid to get the acidity to about 7 or seven depending on what you are doing

1 mole of H2O has 6.023×10²³ atoms

so,

2 moles of H2O will have 1.2046×10²⁴ atoms
