Calculate the molarity of a hydrochloric acid solution that is 18.25% HCl by mass and has a density of 1.20 g/mL.
Container A holds 727 mL of ideal gas at 2.20 atm. Container B holds 134 mL of ideal gas at 4.20 atm. If the gases are allowed to mix together
A compound is heated to produce gas whose molecular mass is to be determined. The gas is collected by displacing water in a water filled flask inverted in a trough of water
reacts with excess Mg to produce 4.20L of H2 gas at 745 mmHg pressure and 35 degrees celcius. What is the molarity of the HCl solution?
