242 g/mol...... hope it helps :)
I believe that the answer is B
Geologists use a metric ruler
Answer: Concentration of is
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
According to stoichiometry,
2 mole of are produced by = 1 mole of
Thus 0.0129 moles of are produced by = moles of
The concentration of is
Answer:
The pH of a 4.4 M solution of boric acid is 4.3
Explanation:
at t=0 cM 0 0
at eqm
So dissociation constant will be:
Give c= 4.4 M and = ?
Putting in the values we get:
Also
Thus pH of a 4.4 M solution is 4.3
