Answer:
3.00 moles of Lithium bromide will be produced
Explanation:
The reaction that takes place is:
By looking at the reaction equation, we can see that<em> the reaction of 1 mol of lithium hydroxide (LiOH) produces 1 mol of lithium bromide (LiBr).</em> Thus, 3.00 moles of LiOH would conversely produce 3.00 moles of LiBr.
Answer:
35 mL
Explanation:
Let the amount of 75% mixture needed be A.
The amount of each solution with their respective concentration to be added together can be expressed as:
0.75A + 0.3(280)...............eqn 1
The addition of the two solution must merge with the expected concentration and this can be expressed as:
0.35(A + 280).............eqn 2
Eqn 1 must be equal to eqn 2, hence:
0.75A + 0.3(280) = 0.35(A + 280)
Solve for A.
0.75A + 84 = 0.35A + 98
0.40A = 14
A = 35
Hence, 35 mL of the 75% mixture will be needed.
