Find the molar mass of Fe_2O_3
2Fe = 2*56 = 112
3O = 3* 16 = 48
Molar Mass = 160 grams
moles= given mass / molar mass
moles = 28 / 160
moles = 0.175 <<<< answer
The relationship between hypotheses, laws and theories is that a law is used to explain hypothesis and theories.
<h3>What is a law, a theory and hypothesis?</h3>
A hypothesis is a tentative conjecture explaining an observation, phenomenon or scientific problem that can be tested by further investigation or experimentation.
A theory is a coherent statement or set of ideas that explains observed facts or phenomena and correctly predicts new facts or phenomena not previously observed.
A law is a statement whose sequence or relationship of phenomena is invariable under certain conditions.
This suggests that a law can be used to explain a theory and hypothesis.

Answer:
Heat, in the form of thermal energy, naturally moves from warmer substances to colder ones. When the ocean is warmer than the atmosphere, it transfers heat — through conduction and radiation — to make the air warmer. ... This redistributes thermal energy and causes changes in the weather.
