How many moles of ammonia are in 0.175 L of a 6.50 M aqueous ammonia solution?

Concentration (C) = number of moles (n) / volume (v)

Therefore

number of moles (n) = concentration × volume

Concentration = 6.50M

Volume =0.175 L = 0.175dm³

n = 6.50 × 0.175

n = 1.138 moles

Moles of ammonia in the solution is

1.138 moles.

Hope this helps
