A solution with a pH of 11 has a [H+] of:<br> 11<br> 1 x 10-3<br> 1 x 10-11<br> 1 x 1011<br> 1 x 103
serious [3.7K]

A solution with a pH of 11 has a [H+] of 1.0\times 10^{-11}

Option B is correct option.

Step-by-step explanation:

A solution with a pH of 11 has a [H+] of= ?

pH=?

Concentration of H+ [H+]= ?

Formula used: pH=-log[H+]

Putting values and finding [H+]

pH=-log[H+]\\\,[H+]\,=10^{-pH}\\\,[H+]\,=10^{-11}\\\,[H+]\,=1.0\times 10^{-11}

So, A solution with a pH of 11 has a [H+] of 1.0\times 10^{-11}

Option B is correct option.

The following data points represent the number of animal crackers in each kid's lunch box.
OLga [1]

Answer:

IQR = 7

Step-by-step explanation:

To get the interquartile range of the set of data, the following steps must be followed:

Datas 4, 4, 6 , 7, 10 , 11 , 12, 14 ,15

Step 1: Rearrange the datas in ascending or descending order if not arranged.

4, 4, 6 7, 10, 11, 12, 14, 15

Step 2:

We will locate the (N+1/4)the cumulative value of the data where N is the total frequency of the data.

N = 4 + 4 + 6 + 7 + 10 + 11 + 12 + 14 + 15

N = 83

N+1/4 = 83+1/4

= 84/4

= 21st cumulative value

On cumulating the values up to the 21st value or more:

4 + 4 + 6 + 7

= 21

Since the 21st value falls on 7, then the interquartile range of the set of data is 7
