Answer:
Answer is Object 2 (which has a density of 1.9 g/cm³).
Explanation;
When object is floating, the weight of that object is less than the up thrust on it.
When an object fully submerged and floating, then the weight of that object is equal to the up thrust on it.
This is known as the Archemide's principle.
Both up thrust and weight depends on the density. Hence, if the density of the solution is high, then the up thrust also high. If the density high, the the weight of the object also high.
Hence, to sink the object in water, that object should be denser than water. Hence, answer is object 3 which has a higher density than water.

Answer:
342.3 g/mol for sugar, 58.44 g/mol of salt, and 84.007 g/mol for baking soda.
Explanation:
This is so because of the formula of molar mass: Molar mass is the mass of a given substance divided by the amount of that substance, measured in g/mol.
Hope this helps :)
Answer:
Al = 2 atoms.
H = 6atoms.
S = 3 atom.
O = 12 atoms
Explanation:
2Al + 3H2SO4 —> Al2(SO4)3 + 3H2
From the balanced equation, the number of atoms of the different elements present on both sides as
Al = 2 atoms.
H = 6 atoms.
S = 3 atoms.
O = 12 atoms
