Answer:
Ammonia (NH3)
Explanation:
its an ionic compound where N nitrogen is bonded to covalent molecules
1.94 moles
I did 35/18.02 because 18.02 is the molar mass of water
During this process. A. Solid turns directly into a Gas.
Answer:
1L
Explanation:
First, let us calculate the number of mole present in 20g of NaOH. This is illustrated below:
Mass = 20g
Molar Mass of NaOH = 23 + 16 + 1 = 40g/mol
Number of mole =?
Number of mole = Mass /Molar Mass
Number of mole of NaOH = 20/40 = 0.5mol
From the question given, we obtained the following data:
Molarity = 0.5M
Mole = 0.5mole
Volume =?
Molarity = mole /Volume
Volume = mole /Molarity
Volume = 0.5/0.5
Volume = 1L
