The pressure of a gas over a soluiton in which the gas is dissolved is proportional to the mole fraction of the gas dissolved in the solution i.e., p∝x p=KB (where KH is Henry.s is Henry.s law constant). Show
Public works tunnelscarry water, sewage or gas lines across great distances. The earliest tunnels were used to transport water to, and sewage away from, heavily populated regions. Roman engineers used an extensive network of tunnels to help carry water from mountain springs to cities and villages....
A new substance has been found with 73 protons and an atomic mass of 192. How many neutrons does it have? How many copper atoms are in a pure copper statue with a mass of 144 kg? You are given a small piece of gold colored material and want to determine if it is actually gold. ...
Since one mole of hydrogen gas has a mass of 2.016 × 10-3 kg, and you have 2.25 × 10-4 kg, you have only 1/8 of a mole. Molar Mass of Compounds To determine the mass of a compound, you count the atoms in the compound by looking at its chemical formula. Look up the masses...
Using Atoms and Ions to Determine Molecular Formulas from Chapter 5 / Lesson 16 32K Molecular formulas are determined using atoms and ions. Learn about different molecular formulas and understand that ions also can determine formulas. Understand coefficients and ionic compounds...
Add the two volumes together to determine the total volume of the final mixture: 100 ml + 250 ml = 350 ml. 4. Convert to a Percentage Use the formulax= (c÷V) × 100 to convert the concentration (c) and volume (V) of the final solution to a percentage. ...
The height of in situ CO2 mole fraction measurements is usually different from that of the model levels where the data are needed; data from short towers, in particular, are difficult to utilize in atmospheric models that do not simulate the surface layer well. Tall-tower CO2 mole fraction ...

Results show that the average hydration velocity in the induction period is proportional to the fraction of the tricalcium silicate surface not covered by sucrose. This suggests a dissolution control of hydration during the induction period – dissolution being strongly inhibited by adsorbed sucrose....
The term "molar solution" refers to the corresponding molarity of a solution. For example, a two molar solution means the molarity of the solution 2 mol/L. Alternatively, it suggests the existence of two moles of solute in one liter of the solution....
