Answer:

V_1=82.6mL

Explanation:

Hello there!

In this case, according to this question, we will need to deal with this dilution problem, because it is asking for the volume of a 12.1-M stock solution of HCl. In such a way, we can use the following equation, under the assumption of no change in the number of moles in the solution:

M_2V_2=M_1V_1

Thus, we solve for the initial volume, V1, as shown below:

V_1=\frac{M_2V_2}{M_1}

And plug in the initial concentration and final concentration and volume to obtain:

V_1=\frac{2000mL*0.500M}{12.1M}\\\\V_1=82.6mL

Regards!

What does the coefficients in a balanced chemical equation represent​
attashe74 [19]

Answer:

th mol

Explanation:

When you balance an equation, you can refer back to the coefficients when calcuating mol and molar mass from the given information about one reactant to antoher reactant ot product. you use the coeffiecients for mol-mol ratio.

for example. if you are given A +3 B -----> 6C + 5D, and you have 10 mol of A and you have to find how many mols of C with 10 mol of A. then you would ratio it as A: C = 10A: 10C= 10(1): 10(6)= 10:60. so with 10 mol A you can make 60 mol C.
