Universe, Stars, Planets, Asteroids
1) the mass of an object gives gravity, the more massive an object is the more gravity it has on the things around it
2)the earth's mass is so much greater than our own that we feel it's gravity stronger than say the moon which has a smaller mass than the earth
3) mass and how far away you are from the object
4)as mass increases so does gravity (sorry I do not remeber the equation but there are some specific ones for different situations between two massive objects)
5) when distance increases, gravity decreases (again I do not remeber by how much)
Answer: Thus 8.41 g was the mass of the original sample
Explanation:
To calculate the moles :
According to stoichiometry :
As 3 moles of 
are produced by = 2 moles of 
Thus 0.103 moles of are produced by =
of
Mass of 
Thus 8.41 g was the mass of the original sample.
