Answer:
2.7 x 10^-1
Explanation:
The places you move to the left are added to the 10 in negative exponential
An electrolytic cell where electrolysis occurs which consists of an electrolyte where current from an outside source is passed through in order to produce an electrochemical cell.
Answer:
I went and searched it up for you
You have the stoichiometric equation. This tells you unequivocally that an
18
⋅
g
mass of water, 1 mole, reacts with a
56.07
⋅
g
mass of quicklime to form a
74.09
⋅
g
mass of slaked lime.
If you don't from where I am getting these numbers, you should know, and someone will be willing to elaborate.
Here, you have formed
6.21
⋅
m

l
of quicklime which requires stoichiometric lime AND water. And thus you need a mass of

In practice, of course I would not weigh out this mass. I would just pour

Answer:
59.2 grams
Explanation:
We are given that 70.4% of the weight of the total 200 g of the concentration is made up of nitric acid, the remaining information is not required to solve the problem. Since water and nitric acid are the only components of the solution, the total weight of water is given by:

There are 59.2 grams of water in this solution.
