Answer:
44 g
Explanation:
The formula for the number of moles (n) is equal to
.
Since we need to find the mass, we derive it from the formula of the number of moles and we get that mass = n x molecular weight .
The molecular weight of
= 12 g/mol (from the carbon) + 19x4 g/mol (from the 4 fluorine atoms)= 88 g/mol
We plug in the numbers in the derived formula for the mass and we get :
mass = n x molecular weight = 0.5 mol x 88 g/mol = 44 g
It's b. calcium
because the outer electron structure in all of that element is similar, they have the same chemical and physical properties.<span />
A. o. I know gamma can I Hope this helps
A now i remember yeah gamma only
The heavy atom count of a casein molecule is 143 I believe
