Answer : The [α] for the solution is, -118.8
Explanation :
Enantiomeric excess : It is defined as the difference between the percentage major enantiomer and the percentage minor enantiomer.
Mathematically,
Given:
% major enantiomer = 86 %
% minor enantiomer = 14 %
Putting values in above equation, we get:
Now we have to calculate the [α] for the solution.
Thus, the [α] for the solution is, -118.8
I believe the number of electrons change because they are incresimg in the atomic number ares
What is the mass, in grams, of 0.00948\,\text {mol}0.00948mol0, point, 00948, start text, m, o, l, end text of phosphoric acid?
ANEK [815]
Answer:
0.929g
Explanation:
The following were obtained from the question.
Number of mole of phosphoric acid (H3PO4) = 0.00948mol.
Mass of H3PO4 =?
The mass in grams of phosphoric acid (H3PO4) can be obtained as follow:
Number of mole of H3PO4 = 0.00948mol.
Molar Mass of H3PO4 = (3x1) + 31 + (16x4) = 3 + 31 + 64 = 98g/mol
Mass of H3PO4 =?
Mass = number of mole x molar Mass
Mass of H3PO4 = 0.00948 x 98
Mass of H3PO4 = 0.929g
