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
