Answer:
pH = 11.7
Explanation:
<u>Given:</u>
[OH-] = 0.00500 M
<u>To determine:</u>
pH of the solution
<u>Explanation:</u>
pH refers to the H+ ion concentration in a given solution whereas pOH indicates the OH- ion concentration.
pH and pOH are related by the following equation:
Here:
When OH- = 0.00500 M
Based on equation(1):
To solve multiply the mL by the mg/ml so 375*40=15000mg
Answer:
No of moles = mass in gram / molar mass
Mass in gram = no of moles× molar mass
Mass in gram = 0.6330× 163.94
103.77 gram
Explanation:
A cell is made of molecules and a molecule is made of atoms. That's the simplest way of putting it. More complicated is that a cell is made up of macromolecules, such as proteins, lipids, etc. A molecule is a particular configuration of atoms.
