An experimental series stack of pem cells produces 2.20 x 108 w of power. if each cell contributes 231 kw, how many cells are in the stack? (round the answer to the nearest whole number.) cells

- 952 cells are there in the stack.

Solution:- From given data, The stack of cells produces W.

Each cell contribution is 231 kW.

Since, 1 kW = 1000 W

Let's convert kW to W and divide the total W of the stack by the W of single cell to get the number of cells as:

= 952 cells

So, from the calculations it is clear that 952 cells are required in a stack to produce W.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
