The law of conservation of mass is must be applied when cooking.
<h3>What is conservation of mass?</h3>
Law of conservation of mass states that mass of any substance will change into another form without any loss of mass, means destroying of mass is impossible.
When we cook food then mass of conservation is applied there, for example we are boiling pulses with water then in that case the amount of formed liquid pulses is equal to the initial mass of solid pulse with water.
Hence law of conservation of mass is applicable during cooking.

Answer:
1.3 x 10²⁴ atoms Fe
Explanation:
To convert moles to atoms, you need to multiply your given value by Avogadro's Number. This causes the conversion to occur because Avogadro's Number exists as a ratio. It is the ratio that allows for the cancellation of units during multiplication. This is why atoms should be in the numerator of your conversion. The final answer should have 2 sig figs to reflect the given value.
Avogadro's Number:
1 mole = 6.022 x 10²³ atoms
2.1 moles Fe 6.022 x 10²³ atoms
--------------------- x ------------------------------- = 1.3 x 10²⁴ atoms Fe
1 mole
The answer should be (4) they are negative subatomic particles and are found surrounding the nucleus. The nucleus is formed by neutrons and protons. Neutrons are neutral and protons are positive.
