mass of 6.584 g. After it is heated, it has a mass of 4.194 g. What is the percentage by mass of water in the hydrate?
Bad White [126]
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

Place the following substances in Order of decreasing boiling point H20 N2 CO
kirill [66]

Answer:

-195.8º < -191.5º < 100º

Explanation:

Water, or H20, starts boiling at 100ºC.

Nitrogen, or N2, starts boiling at -195.8ºC.

Carbon monoxide, or C0, starts boiling at -191.5ºC.

When we place these in order from decreasing boiling point:

-195.8º goes first, then -191.5º, and 100º goes last.
