If 156 mL of wet H2 is collected over water at 24 ∘C and a barometric pressure of 738 torr, how many grams of Zn have been consumed? (The vapor pressure of water is 22.38 torr.)
Gaseous hydrocarbon A 0.271-9 sample of a gaseous hydrocarbon (CxHy) occupies 117 mL at 22.0°C at 735 torr. Calculate the molar mass of this hydrocarbon in g/mol. Express your answer as a number (not scientific notation) without units, for full credit, the last digit of your answer should be within 11 of the correct value, with an appropriate number of significant figures. Molar mass: g/mol. Complete combustion of 1.532 g of this gaseous hydrocarbon (CxHy) yields 4.640 g of carbon...

A sample of hydrogen gas was collected over water at 36 degree C and 855 mm Hg. The volume of the container was 6.50 L. Calculate the mass of H_2(g) collected. (Vapor pressure of water = 44.6 torr at 36 degree C) a. 0.58 g b.9.38 g c.0.55 g d.4.69 g e. 0.27 g
a sample of iron reated with hydrochloric acid. the liberated hydrogen occupied 40.1ml when collected over water at 27 degree celsus at a barometric pressure of 750 torr. what is the mass of the sample of iron? ( Because of the collection of gas over water, the vapor pressure of the water must be subtrated from the barometric pressure to find the pressure of the hydrogen gas)
