The number of moles that are present in 0.75 g of ammonia is 0.04 moles.
What is the relation between mass & moles?
Relation between the mass and moles of any substance will be represented as:
n = W/M, where
- W = given mass = 0.75g
- M = molar mass = 17g/mol
On putting all these values, we can calculate the moles of ammonia as:
n = 0.75g / 17g/mol = 0.04 mole
Hence required moles of ammonia is 0.04 moles.
