Answer:
a i think
Explanation:
because it was the only one that compared something to another
The density can be calculated using the following rule:
density = mass/volume
therefore,
volume = mass/density
we have the mass=22 mg=0.022 grams and density=0.754g/cm^3
substituting in the above equation, we can calculate the volume as follows:
volume = 0.022/0.754 = 0.0291 cm^3
Answer:
known as reactions and metaphorically breaking the witness into telling the truth. I hope this helped:)
Explanation:
Taking into account the definition of molarity, the molarity of a solution that contains 30 moles naoh in 0.80 liters of solution is 37.5
.
<h3>Definition of molarity</h3>
Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

Molarity is expressed in units
.
<h3>This case</h3>
In this case, you have:
- number of moles= 30 moles
- volume= 0.80 L
Replacing in the definition of molarity:

Solving:
<u><em>Molarity= 37.5 </em></u>
<em />
Finally, the molarity of a solution that contains 30 moles naoh in 0.80 liters of solution is 37.5
.
