A certain metal M forms a soluble nitrate salt MNO, Suppose the left half cell of a galvanic cell apparatus is filled with a 450, mM solution of MNO, and the nght 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 20.0 "C. O left Which electrode will be positive? right ? 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 sagnificant digits.
