Answer:
The answer is
<h3>3.75 × 10²⁴ atoms of Al</h3>
Explanation:
To find the number of atoms of Al given it's number of moles we use the formula
<h3>N = n × L</h3>
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
n = 6.23 mol
We have
N = 6.23 × 6.02 × 10²³
We have the final answer as
<h3>3.75 × 10²⁴ atoms of Al</h3>

the third question would be 4, 100%
Answer:
Not sure,12.97(if u get it wrong let me know)
Explanation:
100cm=1m
Then 1297cm=
n=m/M
8.0g÷58.10g/mol=0.14mol
V=n/c
0.14mol÷0.89M=0.16L=1.6×10²mL
While the Moon and Mercury have relatively small volcanoes, those on Venus, Earth and Mars are large and numerous. Earth's volcanoes are still active and Venus' may be, but scientists debate whether Mars' volcanic activity has finished.
