if a solution measured with the miscalibrated meter (above) gave a reading of 6.50 at 20oC, what should be the true pH (give 2 d
ecimal places) of the solution with the correctly calibrated meter at the same temperature
1 answer:
Answer:
Explanation:
Ph is the major of acidity or basicity of a solution. On a scale of 0 to 14
PH = -log 10 ^(H+)
Therefore PH= -log 10^(6.5) =0.81
Therefore PH of the solution is 0.81
This solution is therefore an acidic solution

= 2 × 23 + 2 × 52 + 2 × 16
= 182 grams
1 mole of 
weighs = 182 g
8 moles weigh = 8× 182

or
Isoflavones, quercetin, and anthocyanin are all Flavonoids.
Foreshocks and aftershocks can happen at the same time is not true.
