Be sure your answer has a unit symbol, if necessary, and round it to 2 significant

digits.

M(NO3), Suppose the left half cell of a galvanic cell apparatus is filled with a 150. mM solution of M

of M(NO₂),

A certain metal M forms a soluble nitrate salt

and the right half cell with a 3.00 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 40.0 °C.
