How many grams of CaH2 (Molar Mass = 42.1 g/mol)are needed to generate 14.0 L of H2 gas if the pressure of H2 is 757 torr at 20.0°C
A an aqueous methanol (CH3OH) solution has a mole fraction of 0.430 of methanol. What mass of water would be present in 706 g of this solution?
Determine the mole fraction of each component to at least three significant figures.
Calculate the pH of a buffer solution made by adding 10.0g of anhydrous sodium acetate (NaC2H3O2) to 100 ml of 0.100M acetic acid.
Rank the following bonds from strongest to weakest and provide the bond energy: the bond between hydrogen and oxygen in a water molecule, the bond between sodium and chloride in the NaCl molecule
You have a gas occupying 75L at 800 torr and 315K. What is the volume if the pressure is decreased to 600 torr and the temp is changed to 127 C?
A sample of nitrogen gas at a pressure of 698 mm Hg and a temperature of 86oC, occupies a volume of 14.4 liters. If the gas is heated at constant pressure to a temperature of 116 oC, what the volume of the gas sample will be in L.
