2016-05-29 · In water's case, you will have. 10g ⋅ 1 moleH2O 18.015g = 0.5551 moles H2O. 2 → Moles of water to number of molecules of water. Your conversion factor here will be Avogadro's number, which tells you how many molecules are needed in order to have exactly one mole of a substance. More specifically, you have.

A 32.0 mL sample of hydrogen is collected over water at 20 degree C and 750.0 torr pressure. What is the volume of the dry gass at STP? (Vapor pressure of water at 20 degree C = 17.5 torr) (Dalton's Law of Partial Pressures)

A 320 mL sample of hydrogen is collected over water at 20 C and 7500 Torr from EXTRA extra crea at Pisgah High School 17. A sample of oxygen (O2) of mass 30.0 g is confined in a vessel at 0 oC and 1000.

A sample of carbon dioxide gas has a pressure of 55 mm Hg in a volume of 125 mL. The sample. DVEDV is compressed so that the new pressure of the gas is 78

(assume hydrogen is dry). A sample of hydrogen gas is collected over water in a eudiometer at 32.0°C. The volume of collected gas is 43.9 mL and the atmospheric pressure is 832 mmHg. Using the experimentally collected data, calculate R and the percent error The magnesium metal is reacted with excess hydrochloric acid to produce hydrogen gas.
