Hi.
You can calculate mass percent by dividing the mass by the total mass of the compound & multiplying by 100.
28.8 ÷ (171.2 + 28.8) = 0.144
0.144 · 100 = 14.4
I believe the mass percent of the hydrogen in the compound is 14.4%

If you look at your Chemistry reference table, the answer should be about 62g of NH4Cl. Lining up the lines of solubility and temperature, you should come to that answer.
Answer:
The answer to your question is No
Explanation:
Ionic bonding is a kind of bonding that involves the attraction between oppositely charged ions. That means that one element must have a positive charge and the other a negative charge.
Also, the difference in electronegativity of both elements must be higher than 1.7.
Both Sodium and Aluminum are positively charged then an ionic bond is not possible to be formed.
Difference of electronegativity = 1.61 (Al) - 0.93(Na)
= 0.63
To form an ionic bond the difference of electronegativity must be higher than 1.7.

From the critical reading "B. Nicholas Carr says that Google makes us stupid" reflects the strongest bias
Explanation:
222.5 g
I did it like this:
X/250= 89/100=
22250/100=
222.5
