Answer: 2
Explanation:
To calculate the moles :
According to stoichiometry :
1 mole of 
are produced by = 4 moles of 
Thus 1.18 moles of will be produced by=
of
Mass of 
Thus 85.0 g of will be required and 2 steps are required to get the answer.
The answer to your question is letter D. Secured.
Answer:
0.74M
Explanation:
Step 1 :
Data obtained from the question.
Initial concentration (C1) = 3M
Initial volume (V2) = 185mL
Final volume (V2) = 750mL
Final concentration (C2) =..?
Step 2:
Determination of the new concentration of the solution.
The new concentration of the solution can be obtained by using the dilution formula as shown below:
C1V1 = C2V2
3 x 185 = C2 x 750
Divide both side by 750
C2 = 3 x 185 / 750
C2 = 0.74M
Therefore, the new concentration of the solution is 0.74M
