The mass of hydrogen atoms that is measured at 54 u given the relationship is 89.64×10¯²⁴ g
<h3>Conversion scale </h3>
1 u = 1.66×10¯²⁴ g
<h3>How to determine the mass of hydrogen atoms </h3>
- Mass of Hydrogen (u) = 54 u
- Mass of Hydrogen (g) =?
1 u = 1.66×10¯²⁴ g
Therefore
54 u = 54 × 1.66×10¯²⁴ g
54 u = 89.64×10¯²⁴ g
Thus, the mass of the hydrogen atoms measured at 54 u is 89.64×10¯²⁴ g

Answer:
Via covalent bonds
Explanation:
Atoms in molecules are bonded together via covalent bonds. Covalent bonds are bonds that are formed by sharing of the valence electrons between two atoms.
The atoms can be of the same kind or of different kinds.
- In most molecules, the two atoms are connected by sharing of their valence electrons.
- This way, each atom can attain stability by becoming isoelectric with the nearest noble gas.
- Some molecules are monoatomic, some are polyatomic.
Answer:
The answer is
<h2>5.43 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 250 g
volume = 46 mL
The density is
We have the final answer as
<h3>5.43 g/mL</h3>

Answer:
4.6 moles.
Explanation:
To find the amount of moles of Magnesium, you will need to use Avogadro's number to convert between the two units.
2.77×10^24 moles Mg * (1 mol Mg)/(6.02*10^23)) ≈ 0.46×10^1 moles which equals <u>4.6 moles.</u>
