<span>Solving for the percent composition by mass of sulfur. The formula would be:
%S = mass of sulfur / mass of compound x 100%
Plugging in our data:
%S = 32 amu / 120 amu x 100%
%S = 0.266666 x 100%
%S = 26.66%
Rounded off to two significant numbers it will be 27%. Therefore the answer is number 2.</span>
Answer:
electrons have a negative charge
Explanation:
Answer : The mass of dissolved will be, 0.2365 grams
Explanation :
First we have to calculate the concentration of .
As we know that,
where,
= concentration of = ?
= partial pressure of = 1.65 atm
= Henry's law constant =
Now put all the given values in the above formula, we get:
The concentration of =
Now we have to calculate the moles of
Now we have to calculate the mass of
Therefore, the mass of dissolved will be, 0.2365 grams
