The object of a general chemistry experiment is to determine the amount (in milliliters) of sodium hydroxide (NaOH) solution nee

ded to neutralize 1 gram of a specified acid. This will be an exact amount, but when the experiment is run in the laboratory, variation will occur as the result of experimental error. Three titrations are made using phenolphthalein as an indicator of the neutrality of the solution (pH equals 7 for a neutral solution). The three volumes of NaOH required to attain a pH of 7 in each of the three titrations are as follows: 82.00, 75.65, and 75.43 milliliters.
Required:
Use a 99% confidence interval to estimate the mean number of milliliters required to neutralize 1 gram of the acid

Answer:

x =-5 and y = -6

Step-by-step explanation:

In order to get the answer, I used the elimination/addition method

8y-9x= -3 <— I decided to eliminate the y

5y-8x= 10 <— I decided to eliminate the y

5(8y-9x = -3) <— switch up the number of y from the bottom to multiply

-8(5y-8x= 10) <— switch up the number of y from the top to multiply, but have a negative sign to it

So...our new equation will be....

40y - 45x = -15

+ -40y + 64x = -80

________________________

19x = -95

x = -5

8y-9x= -3

8y-9(-5) = -3

8y+45 = -3

- 45 = - 45

8y = -48

y = -6
