Calculate the number of moles of gas that has a volume of 450.0 ml at 23^{o} C and 745 torr. A sample of hydrogen gas has a volume of 8.56 L at a temperature of 80 degrees Celsius and a pressure of 805 torr. Calculate the number of grams of hydr...
The molar solubility of PbI2 is 1.52 x 10-3 M. Calculate the value of Ksp for PbI2.Calculate the solubility of PbI_2 in units of both moles/ L and g/100 mL. K_{sp} =[ Pb^{2+} ] [I^-] = 1.32 \times 10^{-...
Next, divide the number of grams of solute by the molar mass of the compound to get the number of moles. Step 2 Calculate the molarity of the solution. Molarity is equal to the number of moles of solute divided by the number of liters of solvent, so divide the number of moles by ...
Calculate the number of millimoles (mmol) of citric acid found in 1.00 g of citric acid. (1 mmol = {eq}1 \times 10^{-3} {/eq} mol) Molar Mass: The molar mass is a quantity of substances that defines the mass per mole. This is the key quantit...
The volume of a given mass of a gas can be found by using the ideal gas equation. The ideal gas equation is given as PV=nRT In this equation, P is pressure. V is volume. n is the number of moles of a gas. T is the absolute temperature. ...
