Point of the graph because it’s the point
<h2>
Answer:</h2>
We will need to know Avogadro's number and the molar mass of sucrose for this problem to do dimensional analysis.
- Avogadro's number: 6.022 × 10²³ molecules
- Molar mass of sucrose: 342.2965 g/mol
250g ×
×
= 4.398 molecules
There are <em>4.398 sucrose molecules </em>in 250 grams of sucrose.
Answer:
i need a picture of ur question
Explanation:
Urmmm??????? What is the question
Answer:
Hydroxyl ion concentration is
.
Explanation:
From the given,
pH of the solution = 11.30
pH+pOH = 14
11.30 + pOH = 14
pOH = 14-11.30 = 2.7
The pOH of the solution is 2.7
<u>Concentration of hydroxyl ion:</u>
![2.7= -log[OH^{-}]](https://tex.z-dn.net/?f=2.7%3D%20-log%5BOH%5E%7B-%7D%5D)
![log[OH^{-}]= -2.7=5.08\times10^{-11}M](https://tex.z-dn.net/?f=log%5BOH%5E%7B-%7D%5D%3D%20-2.7%3D5.08%5Ctimes10%5E%7B-11%7DM)
Therefore, hydroxylion concentration is
.
