Answer:
Phosphorus is your answer
Explanation:
M₁=6.584 g
m₂=4,194 g
m(H₂O)=m₁-m₂
w(H₂O)=m(H₂O)/m₁
w(H₂O)=(m₁-m₂)/m₁
w(H₂O)=(6.584-4.194)/6.584=0.3630 (36.30%)
the percentage by mass of water in the hydrate 36.30

Answer:
4.86 moles of HCl
Explanation:
1. First write the balanced chemical equations involved in the process:
2. Calculate what amount of is formed in the first reaction.
As the yield of each reaction is 90.0%, the amount of produced is the following:
3. Calculate the amount of HCl produced.
The total amount of HCl produced with a 90.0% yield is:
