To determine the number of moles in 73.5 g of sodium sulfide (Na2S), you first need to calculate the molar mass of Na2S, which is 78.04 g/mol. Then divide the given mass by the molar mass to find the number of moles. Therefore, 73.5 g / 78.04 g/mol = 0.942 moles of sodium sulfide.

How many moles of hydrogen gas is required to completely react with chlorine in the following reaction that has a pressure of 735 torr at 34 C in a 450 ml container according to the reaction. H2 Cl2 2?
To find the number of moles of hydrogen gas, we first need to calculate the number of moles of chlorine gas using the ideal gas law formula (PV = nRT). Once we have the moles of chlorine gas, we can determine the moles of hydrogen gas needed for the reaction. In this case, the stoichiometry of the reaction states that 1 mole of chlorine gas reacts with 1 mole of hydrogen gas, so the required moles of hydrogen gas will be equal to the moles of chlorine gas.
A glass column is filled with mercury and inverted in a pool of mercuryThe mercury column stabilizes at a height of 735 mm above the pool of mercuryWhat is the pressure of the atmosphere?
The height of the mercury column in the tube represents the balance between the atmospheric pressure pushing down and the pressure exerted by the column of mercury pushing up. With a height of 735 mm, the atmospheric pressure can be calculated as 735 mm Hg or 735 torr.
How much does one mole of francium weigh?
The molar mass of francium is approximately 223 grams per mole. Therefore, one mole of francium would weigh around 223 grams.
How large a volume is needed to contain 21 grams of silver?
The density of silver is 10.49 grams per cubic centimeter. To find the volume needed to contain 21 grams of silver, divide the mass by the density: 21 grams / 10.49 g/cm^3 ≈ 2 cubic centimeters.
