Aseries stack of alkaline cells produces 4.524 kw of power. if each cell contributes 14.5 w, how many cells are in the stack? (round to the nearest whole number.) 3 66 312 3,205

The answer would be 312 cells. 

Before you can answer this, you need to make sure that your units are the same. 

The stack produces 4.524kW of power. Kilo means 1000, so 1 kW or kilowatt is equal to 1,000 watts.  So if we convert that into watts, then the stack produces 4,524W.  Here is how you convert it:

x  = 4,524W. 

Now you can solve how many watts each of the cells produce because your units are now the same. Just divide the total power by the power produced by one cell. 

4,542W ÷ 14.5W = 312W
