Potassium Chloride = KCl
KCl has a molar mass of: 39.0983g+35.4530g=74.5513g
The number of moles of KCL we are adding is:
2g/(74.5513g/mol) = 0.02683 mol
But you have to keep in mind that salts in
water dissociate:
KCl -> K+ + Cl-
So 1 mole KCl is 2 osmoles (because it’s
two particles)
So if you add 0.02683 moles, you are adding
0.02683*2 = 0.05366 osmoles.
If you dissolve them in 1 liter, you have a solution 0.05366 OsM = 53.66 mOsM
D5W = dextrose 260 mOsM
1/2 Normal Saline =
has half of the normal saline concentration - a normal saline solution has the
same sodium chloride concentration as blood serum = 154 mOsm
You have to sum up all the osmolarities:
<span>= </span>53.66 mOsM + 154 mOsM + 260 mOsM = 467.66 mOsM
B i hope this help good luck
It would be CaF2 because you will need to balance then so since F is -1 it'll need another one to balance with Ca +2
Atomic Mass will be 23 the new magnesium formed will be its isotope of magnesium.
We know that,
In stable condition
Number of electrons = Number of protons
Atomic number represents number of proton .
So, here number of proton is 12
Therefore, number of electron is 12
We know that -
Atomic mass = number of protons +Number of neutron
So if magnesium loses one neutron i.e. new number of neutron is 11
then its atomic mass changes.
New atomic mass will be
Atomic mass = 
Atomic mass = 23
This new element with atomic mass 23 and atomic number 12 is the isotope of magnesium.
