Answer:
0.5455
Explanation:
The moles of benzene in the process stream in 1 sec = 450 moles
The moles of toluene in the process stream in 1 sec = 375 moles
So, according to definition of mole fraction:
Applying values as:
<u>Mole fraction of benzene in the process stream = 0.5455</u>
The mass percent of oxygen in Nickel()sulfate is
percent.
At first, we look up the atomic masses for the element from the periodic table.
The atomic masses are found to be:
- Ni is
- S is
- O is
Next, we determine how many grams of each element are present in one mole of
of Ni
of S
of O
The mass of one mole is:
So, The mass percent of oxygen
percent.
To learn more about Mass percent, refer to:
