sorry it's not actually chemistry, I just couldn't find the science tag. Anyway my question is looking back at the distribution of other natural resources (fossil fuels and ores) how does this information explain why so much farmland occurs in the midwest region?

50.23 i believe is correct but don't quote me on that.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
