Answer:
<h3>The answer is 7.85 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula

volume = final volume of water - initial volume of water
volume = 13.91 - 12 = 1.91 mL
We have

We have the final answer as
<h3>7.85 g/mL</h3>

Answer:
Avogadro's number is a proportion that relates molar mass on an atomic scale to physical mass on a human scale. Avogadro's number is defined as the number of elementary particles (molecules, atoms, compounds, etc.) per mole of a substance. It is equal to 6.022×1023 mol-1 and is expressed as the symbol NA.
<u>Answer:</u> The mass of the nitrous oxide gas produced is 0.011 kg.
<u>Explanation:</u>
To calculate the mass of the gas, we use the formula:

We are given:
Specific density of the gas = 
Mass of the gas = ? kg
Volume of the gas =
(Conversion Factor:
)
Putting values in above equation, we get:


Hence, the mass of the nitrous oxide gas produced is 0.011 kg.
