1 answer:
Answer:
<h2>Volume = 9.29 mL</h2>Explanation:
Density of a substance can be found by using the formula
From the question
Density = 11.3 g/mL
mass = 105 g
Substitute the values into the above formula and solve for the volume
That's
Cross multiply
11.3v = 105
Divide both sides by 11.3
v = 9.29203
We have the final answer as
<h3>Volume = 9.29 mL</h3>Hope this helps you

Answer:
The number of moles of O atom in mol of
= 1.6
Explanation:
1 molecule of contains 2 atoms of O
So, molecules of
contains
atoms of O.
We know that 1 mol of an atom/molecule/ion represents numbers of atoms/molecules/ions respectively.
So, molecules of
is equal to 1 mol of
.
atoms of O is equal to 2 moles of O atom.
Hence, 1 mol of contains 2 moles of O atom.
Therefore, mol of
contains
moles of O atom or 1.6 moles of O atom.
