Answer:
"23.896%" is the right answer.
Explanation:
The given values are:
Mass of NaCl,
= 51.56 g
Mass of H₂O,
= 165.6 g
As we know,
⇒ Mass of solution = 
= 
= 
hence,
⇒ 
Answer:
2.19L
Explanation:
Information from the question include:
V1 (initial volume) = 2.3L
P1 (initial pressure) = 725mmHg
P2 (final pressure) = 760mmHg
V2 (final volume) =?
With the Boyle's law equation P1V1 = P2V2, the final volume can easily be obtain as follow:
P1V1 = P2V2
725 x 2.3 = 760 x V2
Divide both side by 760
V2 = (725 x 2.3)/760
V2 = 2.19L
Therefore, the new volume of the gas at standard pressure is 2.19L
A halide ion is a halogen atom bearing a negative charge. The halide anions are fluoride (F−), chloride (Cl−), bromide (Br−), iodide (I−) and astatide (At−). Such ions are present in all ionic halide salts. Halide minerals contain halides.
