Answer:
A (True)
Explanation:
Because ibuprofen has a chiral carbon center (carbon bonded to 4 distinct groups of atoms).
This means that a mixture of ibuprofen can rotate plane-polarized light equally in both the clockwise and counterclockwise direction.
I believe it’s C.) Mass. Hope I’m right.

Answer:
Number of moles of solute = 0.6 mole
Mass =13.8 g
Explanation:
Given data:
Number of moles of sodium = ?
Volume = 2.0 L
Molarity = 0.30 M
Mass in gram of sodium= ?
Solution:
<em>Number of moles:</em>
Molarity = number of moles of solute / volume in litter
Number of moles of solute = Molarity × volume in litter
Number of moles of solute = 0.30 M × 2.0 L
Number of moles of solute = 0.6 mole
<em>Mass in gram:</em>
Mass = Number of moles × molar mass
Mass = 0.6 mole× 23 g/mol
Mass =13.8 g
