Answer:
26 grams of D will be produced.
Explanation:
The reaction is given by:
A + B -----> C + D
Mass of A reacted = 21 g
Mass of B reacted = 22 g
Mass of C formed = 17 g
Mass of D formed = m =?
According to law of conservation of mass, the total mass of the reactants used is equal to the total mass of the product formed.
Then:
mass of A reacted + mass of B reacted = mass of C formed + mass of D formed
21 + 22 = 17 + m
m = 26 g
The most concentrated solution is b
Answer:

Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the volume of the new solution by using the general formula of dilution:

In such a way, we solve for the final volume, V2, to obtain:
