Answer:
The volume (in ml) of a 3.57 M solution of 
that contains 0.884 moles of is 247.61g mL
Explanation:
According to the definition of Molarity
which sates
"The amount of moles of a substance present in one litre of the solution is called as Molarity."
3.57M solution implies that 1000 mL of the solution conatins 3.57Moles of
Hence , 3.57 moles of is present in the 1000 ml of solution
Now,
In 1 mole of is present in the =
ml of solution
Similarily ,
In 0.884 moles of is present in the 
of solution= 247.61g mL
Answer:
Hummingbirds have a very high metabolism and must eat all day long just to survive. They consume about half their body weight in bugs and nectar, feeding every 10-15 minutes and visiting 1,000-2,000 flowers throughout the day.
Answer:
In general, the energy needed to remove an electron (the ionization energy) increases as the atomic number increases across a period.
Explanation:
Each additional proton increases the attraction between the nucleus and the electron.
Thus, it takes more energy to remove an electron as you add extra protons.
The mass percent of sugar in the solution is 1.225%
<u><em>calculation</em></u>
mass percent = [(mass of solute /mass of solution ) x 100]
mass of solute ( mass of a substance that dissolve in another substance)
= 2.45 g
mass of solution( mass of a substance that dissolves a solute) =200.0 g
Therefore mass percent = 2.45 g/200.0 g x 100 = 1.225% of sugar in solution
