The number of moles in each sample will be 0.391 moles, 30.7 moles, 0.456 moles, and 1350 moles
<h3>What is the number of moles?</h3>
The number of moles of a substance is the ratio of the mass of the substance to the molar mass.
In other words; mole = mass/molar mass.
Thus:
- moles of 18.0 g = 18.0/46
= 0.391 moles
- moles of 1.35 kg = 1350/44
= 30.7 moles
- moles of 46.1 g = 46.1/101.1
= 0.456 moles
- moles of 191.8 kg = 191800/142
= 1350 moles

Answer:
Answer: A. Gases are easily compressed because of the low density.
Explanation:
Answer:
<h2>18 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
volume = final volume of water - initial volume of water
volume = 62 - 52 = 10 mL
From the question we have
We have the final answer as
<h3>18 g/mL</h3>
