Answer:
0.015 moles
Explanation:
- One mole of a compound contains molecules equivalent to the Avogadro's constant, 6.022 × 10^23.
- That is, 1 mole of a compound will have 6.022 × 10^23 molecules.
In our case, We are given 8.96 x 10^21 molecules of KBr
We need to find the number of moles in 8.96 x 10^21 molecules
1 mole of KBr = 6.022 × 10^23 molecules.
8.96 x 10^21 molecules = ?
Therefore;
(1 × 8.96 x 10^21 molecules ) ÷ 6.022 × 10^23 molecules.
= 1.488 × 10^-2 moles
= 0.01488 moles
= 0.015 moles
Answer: B. Surface Tension
Explanation:
It is the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area.
Answer:
B because they aren’t moving there solid and compacted

100 mL of water weighs 100 g.
If 100 mL of a liquid that weighs only 20g, it cannot be water because of the great difference in density, unless there is an enormous error in the weighing process.
