Answer :
Answer:
C
Explanation:
Since Moles=mass/molar mass
Mass=432g
Molar mass=261g/mol
Moles=1.65mol
The number of moles in 432g Ba(NO3)2 are 1.65 mol.
What are moles?
Moles can be defined as the amount of substances present in a system that contain the same number of entities as the number of atoms in 12g of carbon 12.
Moles = Given mass / Molar mass
Given mass = 432 g
Molar mass of Ba(NO3)2 = 261.3 g
Moles = 432/261.3
= 1.65 moles
Hence, C is the correct option
