<u>Answer:</u> The moles of NaOH are 0.25 moles.
<u>Explanation:</u>
To calculate the number of moles, we use the following formula:
Calculations for the moles of NaOH:
Given mass of NaOH = 10 g
Molar mass of NaOH = 40 g/mol
Putting values in above equation, we get:
Hence, the moles of NaOH are 0.25 moles.
Answer:
<u>The atoms move more </u><u>quickly</u><u> and closer together</u>.
Answer:
24.2 mL.
Explanation:
<em>Assuming constant temperature</em>, we can solve this problem using <em>Boyle's law</em>, which states:
Where:
We <u>input the data</u>:
- 0.98 bar * 25 mL = 1.013 bar * V₂
And <u>solve for V₂</u>:
The closest option is the second one: 24.2 mL.
