Answer:
24g of NaOH are required
Explanation:
Molarity, M, is an unit of concentration widely used in chemistry defined as the ratio between moles of solute (In this case, NaOH), and volume of solution in liters.
We can find the moles of NaOH and its mass with the volume and desired concentration as follows:
<em>Moles NaOH:</em>
400.0mL = 0.400L * (1.50mol / L) = 0.600 moles NaOH
<em>Mass NaOH -Molar mass: 40.0g/mol-:</em>
0.600 moles * (40.0g / mol) =
<h3>24g of NaOH are required</h3>
Answer:
The answer is
<h2>241.15 kPa</h2>
Explanation:
To find the pressure in kilopascals we must first find the pressure in Pascal
To find the pressure in Pascal we use the conversion
1 atm = 101 , 325 Pa
If 1 atm = 101325 Pa
then 2.38 atm = 2.38 × 101325
= 241153.5 Pa
Converting it into kPa we have the final answer as
<h3>241.15 kPa</h3>
