The other person should of stopped there they started making up steps XD
We have 16g of helium and the molar mass of He is 4.002 Amu.
Mole = 16g/4.002Amu
Mole = 3.998 mol
Mole = 4.00 mol
There are 6.02 x 10^23 molecules in a mol so there are 4 times of 6.02 x 10^23 molecules of helium. Quite a lot huh! :)
4 moles of He
We have, 16g of He (Helium).
To calculate the number of moles in given amount of a substance, we have the formula.
Here, we have 16g of He.
Molar mass of He is 4g
On substituting the values in the equation, we get
the answer is:
B. 4.0 mol
hope this helps :)
1 mole MgS2O3 136.43 g
? moles MgS2O3 163 g
moles MgS2O3 = 163 x 1 / 136.43
moles MgS2O3 = 163 / 136.43 => 1.1947 moles
Mole (mol): The number of particles (atoms or molecules) in a.
sample of element or compound with a mass in grams equal to the.
atomic (or molecular) weight.
6.02 x 10^23
= 8.43 x 10^-8 moles.
16/4 = 4
answer; i believe that the correct answer to this statement is (exoticism); //
exoticism was a trend where musicians created music based on a far off foreign
