It depends on where your yields sign is, but usually it's the elements/ compounds in the front. In this case, HCL and NaOH
This is true as some parts cannot be checked but the radioactive substances can be used in x-rays
Of what type of solutions

Answer:
Explanation:
We're asked to calculate the number of atoms of
Ca
in
153
g Ca
.
What we must first do is convert the given mass of calcium to moles of calcium, using its molar mass (referring to a periodic table, this is
40.08
g
mol
):
153
g Ca
(
1
mol Ca
40.08
g Ca
)
=
3.82
mol Ca
Using Avogadro's number,
6.022
×
10
23
particles
mol
, we can calculate the number of atoms present:
3.82
mol Ca
(
6.022

10
23
atoms Ca
1
mol Ca
)
=
2.30
×
