Photochemical equivalence law
First, you would add the products: 0.4 + 6.01 = 6.41 g
Then, to get the mass of Iron required, you would do 6.41 - 5.0 = 1.41
This is because in the conservation of mass principle it states,
mass of reactants = mass of products.
Answer:
Approximately 206 grams.
Explanation:
How many moles of sulfuric acid 
are there in this solution?
.
The unit for concentration "
" is equivalent to mole per liter. In other words, 
. For this solution, the concentration of is 
.
.
What's the mass of that 
of ?
Start by finding the molar mass 
of .
Relative atomic mass data from a modern periodic table:
- H: 1.008;
- S: 32.06;
- O: 15.999.
.
.
.
In other words, the chemist shall need approximately 206 grams of to make this solution. As a side note, keep in mind that the 206 grams of also take up considerable amount of space. Therefore it will take less than 5.00 L of water to make the 5.00 L solution.
Answer:
Indirect. I don't think it's cycling and it's not direct or constant
