Asample of carbon monoxide gas was collected in a 2.0l flask by displacing water at 25 degrees celsius and 810 mmhg. calculate the mole fraction and number of co molecules in the flask. the vapor pressure of water at 28 degrees celsius is 28.3 mmhg.

What is a property of a double replacement reaction

If i add water to oil what will happen

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
