Physics is the branch of science that deals with the structure of matter and how the fundamental constituents of the universe interact. It studies objects ranging from the very small using quantum mechanics to the entire universe using general relativity.
Answer : The percentage (by mass) of
in the mixture is 20 %
Explanation :
As we are given that, 10 % sulfur by mass that means 10 grams of sulfur present in 100 grams of mixture.
Mass of sulfur = 10 g
Mass of mixture = 100 g
Now we have to calculate the mass of
.
As, 32 grams of sulfur present in 64 grams of 
So, 10 grams of sulfur present in
grams of 
Thus, the mass of
is 20 grams.
Now we have to calculate the percentage (by mass) of
in the mixture.


Therefore, the percentage (by mass) of
in the mixture is 20 %
