how many moles of magnesium oxide are produced by the reaction of 1.82 g of magnesium nitride with of water? mg3n2 + 3 h2o → 2 nh3 + 3 mgo group of answer choices

level 4 to level 2 : ))

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.
