Answer:
9.2
Explanation:
M = mol of solute/L of solution
L/325 mL x 1000 mL/L = 0.325 L
3.0/0.325 = 9.2

Bromine and Iodine are both
totally soluble in mineral oil because these substances are all made up of
non-polar molecules. And because water is a polar molecule, Bromine and Iodine
is not soluble in it.
Non polar solvents contain
bonds that have similar electronegativity, an example of this is carbon and
hydrogen such as gasoline. Some other examples are pentane, hexane, benzene
and toluene.

Answer:
8.72 × 10^5 moles
Explanation:
To find the number of moles in 5.25 x 10^29 molecules of sucrose, we divide the number of molecules by Avagadro constant (6.02 × 10²³ molecules). That is;
no. of moles = no. of molecules ÷ 6.02 × 10²³ molecules
In this case of sucrose, no of moles contained is as follows;
5.25 × 10^29 ÷ 6.02 × 10²³
5.25/6.02 × 10^ (29-23)
0.872 × 10^6
= 8.72 × 10^5 moles
Answer:
A
Explanation:
The strength of the gravitational force between two objects depends on mass and distance. The object with the greatest mass would be the car.
