Answer:

The number of hamburgers is 109.

Explanation:

Let h = number of hamburgers

Let c = number of cheeseburgers

The total number sold gives us the equation below.

h + c = 327

"The number of cheeseburgers sold was two times the number of hamburgers sold.

This gives us the equation

c = 2h

Now we substitute c with 2h in the first equation and solve for h.

h + 2h = 327

3h = 327

h = 109

The number of hamburgers is 109.

If it requires 75.0mL of 0.500M NaOH to neutralize 165.0 mL of an hcl solution what is the concentration of the hcl solution
Kaylis [27]

Answer:

0.027 M HCl

Explanation:

The chemical equation of the neutralization is:

1 NaOH + 1 HCl -> 1 H2O + 1 NaCl

Because the ratio of NaOH and HCl is 1:1 you can use the M1V1=M2V2 formula.

(75 mL)(0.5 M NaOH) = (165 mL)(M HCl)

It requires 0.027 M HCl.
