Answer:
12g of rain 12g of snow 12g of ice
Explanation:
yes this was answered by a 6th grader no joke so what happens is rain would basically classified as water so that would sink all the way to the bottom. Then snow cause that is somewhat like a solid mixed up with water so that would be second and then ice is just a plain old solid i hope i answered your question
Answer: no. Moles= 1.382moles
Explanation:
No. Of moles = mass/molar mass
NB : molar mass Al2O3= (27×2)+(16×3)= 102
n= 141/102 = 1.382moles
<span>Isotopes are atoms of the same element with the same number of protons and same number of electrons but with <span>different
number of neutrons. They differ in the number of neutrons that is why
they also differ in mass numbers. Since they have the same number of
protons, they have the same atomic number.
For instance, when the
nucleus of the isotope with a 68.926 amu, there are 30 protons and 39
neutrons in the nucleus. The best example for this is Zn (zinc-69
isotope) and Ga (gallium-69 isotope) which has 68.926 amu and 68.925 amu
respectively.

Given parameters:
Mass of H₃PO₄ = 49g
Unknown:
Number of moles = ?
Solution:
To find the number of moles of a given specie;
number of moles =
Molar mass = 3(1) + 31 + 4(16) = 98g/mol
Input the parameters and solve;
Number of moles = = 0.5mole
The number of moles is 0.5mole
