Answer:
Explanation:
Let the farmer had n no of bags of cabbage .
given to hospital = n / 4
given to school = 1/2 x 3n /4
= 3n / 8
given to grocer = 1 / 3 x (3n / 8 )
= n / 8
No of bags distributed
= n / 4 + 3n / 8 + n / 8
= 6n / 8
Remaining bag
= n - 6n / 8
= 2n / 8
According to question
2n / 8 = 6 + n / 8
n / 8 = 6
n = 48 .
Answer:
pOH = 8.19
Acidic solution (pH < 7.0)
Explanation:
The pOH of the solution is defined as:
pOH = - log [OH⁻]
Since we have [OH⁻] = 6.5 x 10⁻⁹ M, we calculate the pOH as follows:
pOH = - log (6.5 x 10⁻⁹) = 8.19
To know if the solution is acidic, neutral or basic, we have to calculate the pH from the value of pOH:
pH + pOH = 14
⇒ pH = 14 - pOH = 14 - 8.19 = 5.81
The solution is acidic because pH < 7.0.
