Determine the error in the molar mass of Mg(ClO4)2. If 0.982(+/- 0.002)g is dissolved in a 250 mL (+/-0.08 mL) volumetric flask and water added to the mark, what is the concentration and error in the concentration of ClO4-?
Calculate the change in pH that occurs in each of the the solutions listed below as a result of a tenfold dilution with water. Round calculated values for pH to three figures to the right of the decimal point. (b) 0.0500 M HCL (d) 0.0500 M
Two manufacturing plants need 1.0x104 kg of Al each week. One plant produces the Al from bauxite (Al2O3) and the other produces Al from recycled cans. Recovering Al via recycling consumes only 5% of the energy it takes to manufacture aluminum from..
