Answer:
3g of NaI is needed to prepare 400.0 mL of 0.0500 M NaI solution.
Explanation:
A 0.0500M solution means that is 0.0500 moles of NaI per every 1000 mL of solution. Thus, to prepare 400mL:
Also, the molar mass of NaI is 127g/mol + 23g/mol = 150g/mol
Consequently, multiplying the molar mass of NaI by the moles the necessary mass is obtained:

Answer:
Racemic mixture of racemate
Explanation:
A racemic mixture or racemate is a mixture with the same amount of left- handed and the right handed enantiomers.
The main characteristic of a racemic mixture is that is optically inactive, that means that can not rotate polarized light. Also a racemic mixture has other different physical properties than the pure enantiomers.
