Answer:
<h3>The answer is 8.00 moles</h3>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
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 we have
We have the final answer as
<h3>8.00 moles</h3>
Hope this helps you
we find the number of moles with the formula
pV=nRT
27C=300k
3.2*30=n*0.082*300
n=96/24.6=3.9 moles
we have the mass ant the number of moles so we can calculate the molar mass
283.3/3.9=72.64g/moles
that means X's mass is 72.64/2=36.3 so the element is Kr(Kriptonium)
The answer is c) to repair and replace other cells.
Cell division is the replication of cells by dividing itself into two, it does not prevent replication. Cell division does not make glucose either and cell division does not make ATP.
