A certain metal M forms a soluble sulfate salt M₂(SO4). Suppose the left half cell of a galvanic cell apparatus is filled with a 45.0 mM solution of M₂(SO4)3 and the right half cell with a 4.50 M solution of the same substance. Electrodes made of M are dipped into both solutions and a voltmeter is connected between them. The temperature of the apparatus is held constant at 35.0 °C. Which electrode will be positive? What voltage will the voltmeter show? Assume its positive lead is connected to the positive electrode. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits. left O right 0 x10 X
