What is the molality of a solution formed by dissolving 1.70 mol of KCl in 15.0 mol of water (MM of water = 18.02 g/mol),
when 0.273-gm of Mg is reacted at high temperatures with N2 to produce 0.378-gm of a solid, MgxNy. Calculate the empirical formula of the product.
My dilemma is that I'm unsure on how to find the actual limiting reactant, and what information I should use. There's too much given; but from my introspection, we only need 1-Octene and the Pt catalyst
If the solubility of a gas is 7.5 g/L at 404 kPa pressure, what is the solubility of the gas when the pressure is 202 kPa?
Determine how many grams of Ammonia are needed to produce 130 grams of hydrogen flouride?
A compound composed of sulfur and fluorine is found to contain 25.24% by mass of sulfur. If the molar mass of the compound is 254.11 g/mol, what is its molecular formula?
A sample containing 4.80 g O2 of gas has a volume of 15.0 L. Pressure and temperature remain constant. What is the new voume if 0.500 mole O2 gas is added.
Acrylonitrile, C3H3N (53.07 g/mol), is used in the synthesis of a variety of plastics. What mass of acrylonitrile can be produced from a mixtur.
