Answer:
it would sink to the bottom of the ocean and break in half
Explanation:
Answer:
3.02x10²⁴
Explanation:
To solve this problem we need to use <em>Avogadro's number</em>: It is the number of units (usually atoms or molecules, in this case it's trucks) contained in one mol: 6.023x10²³.
We <u>multiply the given number of moles times Avogadro's number</u>:
5 * 6.023x10²³ = 3.02x10²⁴
So five moles of trucks would be 3.02x10²⁴ trucks.
<u>Explanation:</u>
<u>Similarity between the two:</u>
Molecular formula and structural formula gives the exact number of atoms of different chemical elements that are present in a compound.
<u>Difference between the two:</u>
Structural formula gives us the relative positions of the atoms that are present in a compound whereas molecular formula does not give us the relative positions of the atoms. But it gives us the ratio of atoms in a given compound.
Q=mcΔT
q=(125g)(0.446 J/(g x °C))(78°C - 23.5°C)
q=(125 g)(0.446 J/(g x °C))(54.5°C) (Be sure to cancel all similar units)
q= 3038.375 J

Answer: 386.67 g/mol </h3>
Explanation:
Molar Mass = Mass ÷ Mole
= 0.406 g ÷ 0.00105 mol
= 386.67 g/mol
∴ molar mass of cholesterol = 386.67 g/mol
