Explanation:
The gravitational force between two 50kg objects could be less than the gravitational force between a 50kg and a 5kg object if the two 50kg objects are much farther apart.
1740 g because the molar mass is 133.33g/mol, mulitplied by 11.37 mol = 1743.36. 1740 is closest and it may be a bit off depending on how many sig figs are used for the molar mass. So 1740g

Answer:
Water (H2O) is made from 2 atoms of hydrogen and 1 atom of oxygen. A mole of water molecules would be 2 moles of hydrogen atoms plus 1 mole of oxygen atoms. From the periodic table we see the atomic weight of hydrogen is 1.0079 and the atomic weight of oxygen is 15.9994
