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.
Explanation:
Answer:
The value of an integer x in the hydrate is 10.
Explanation:
Molarity of the solution = 0.0366 M
Volume of the solution = 5.00 L
Moles of hydrated sodium carbonate = n
Mass of hydrated sodium carbonate = n= 52.2 g
Molar mass of hydrated sodium carbonate = 106 g/mol+x18 g/mol
Solving for x, we get:
x = 9.95 ≈ 10
The value of an integer x in the hydrate is 10.
Tell your teacher. They'll know what to do and it's best to report it to them.
Answer:
Explanation:
If the choices are:
A. Molarity is defined as moles of solute per liter of solvent.
B. % by mass is defined as grams of solute per 100 g of solvent.
C. % by volume is defined as grams of solute per 100 L of solution.
D. Molarity is defined as moles of solute per liter of solution.
E. All of the above.
then the ans is E
