melomori [17]

pH of the acetyl choline solution before incubation = 7.65

$[H_{3}O^{+}]=10^{-7.65}=2.24*10^{-8}M$

pH of the solution after incubation = 6.87

$[H_{3}O^{+}]=10^{-6.87}=1.35*10^{-7}M$

The difference in concentration of hydronium ion before and after incubation

= $1.35*10^{-7}M$ - $2.24*10^{-8}M$ = $1.126*10^{-7}M$

This difference in hydronium ion concentration can be attributed to the increase in the concentration of acetic acid, which is formed when acetylcholine is hydrolyzed by acetycholinesterase. The mole ratio of acetylcholine to acetic acid is 1:1.

Therefore the moles of acetylcholine = $15 mL * \frac{1L}{1000mL}*\frac{1.126*10^{-7}mol }{L}=1.689*10^{-9}mol$

I/3 of 12 = 2/3 of please help at 11 o'clock am it needs to be done

Nostrana [21]

Answer:

Explanation:

This question is seeking for an equivalent of one expression. The first expression says 1/3 of 12, which means 1/3 × 12 = 4. To find 2/3 of a number that will give us 4, we say

Since; 1/3 of 12 is 4

Then, 4 = 2/3 of x, where x is the number, which when multiplied by two-third (2/3) will result to 4.

4 = 2/3 × x

4 = 2x/3

Cross multiply

2x = 3 × 4

2x = 12

x = 12/2

x = 6.

This means that; 1/3 of 12 = 2/3 of 6
