How many grams of CrNO33 are required to prepare 500.0 mL of an aqueous solution which has a Cr3 concentration of 2.08 M?
To determine the grams of Cr(NO3)3 needed, first calculate the molar mass of Cr(NO3)3. Then, use the formula: moles = Molarity x Volume (in L) to find the moles of Cr(NO3)3. Finally, multiply the moles by the molar mass to get the grams.
