Calculate the mass/volume percent (m/v) of 13.0 g nacl in 49.5 ml of solution.

mass/volume percent (m/v) = mass of solute*100/volume of solution

mass of solute that is NaCl is 13 g

Volume of solution is 49.5 mL

Mass/Volume percent=13*100/49.5

=26.26

(m/v) % = [mass of solute (g) / volume of solution (mL)] x 100

a) [2.50/50.0] x100 =5.00%

b) [7.5/120] x100=6.3%

Explanation:

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.
