Answer:
6.46 × 10⁻¹¹ M
Explanation:
Step 1: Given data
pH of the solution: 3.81
Step 2: Calculate the pOH of the solution
We will use the following expression.
pH + pOH = 14.00
pOH = 14.00 - pH = 14.00 - 3.81 = 10.19
Step 3: Calculate the concentration of OH⁻ ions
We will use the definition of pOH.
pOH = -log [OH⁻]
[OH⁻] = antilog -pOH = antilog -10.19 = 6.46 × 10⁻¹¹ M
Endocytosis

Exocytosis
Secretion of material out of the plasma membrane
The buret should be conditioned before loading it with the titrant.
<h3>What is a Buret?</h3>
This is defined as laboratory apparatus which is used in quantitative chemical analysis to measure the volume of a liquid or a gas.
It should be conditioned with the titrant solution to prevent dilution from occurring as a result of cleaning it with water.

Answer:
240g
Explanation:
Using the equation m=pV, where m=mass, p=density, and V=Volume
m=(6)(40)=240
m=240
