A King in ancient times agreed to reward the inventor of chess with one grain of wheat on the first of the 64 squares of a chess board.?


On the second square the King would place two grains of​ wheat, on the third​ square, four grains of​ wheat, and on the fourth square eight grains of wheat. If the amount of wheat is doubled in this way on each of the remaining​ squares, what is the total weight in tons of all the wheat that will be placed on the first 49 ​squares?

(Assume that each grain of wheat weighs​ 1/7000 pound. Remember that 1 ton equals 2000​lbs.)

Update 2:

The total weight of the wheat that will be placed on the first 49 squares is ___ tons.

​(Use scientific notation. Use the multiplication symbol in the math palette as needed. Do not round until the final answer. Then round to six decimal places as​ needed.)

    80,421,421.9173 tons ( a bit over 80 million tons)

    (1/7000) x(2^50)/2000
