Answer:
Molarity= 0.071M
Explanation:
Molar mass of NaNO3= 23+14+(16*3)=85
n= m/M = 30/85= 0.353mol
V= 5L
Applying
n= CV
0.353= C×5
Simplify
C= 0.071M
Answer:
4 mL
Explanation:
Use the density formula, d = m/v
Plug in the density and mass to solve for v:
4 = 16/v
4v = 16
v = 4
So, the volume is 4 mL
Answer: 8.25 moles of oxygen are produced.
Explanation: The reaction follows:
By Stoichiometry,
As, 4 moles of Aluminium is produced by 2 moles of aluminium oxide
11 moles of aluminium will be produced by = 
Now, 2 moles of aluminium oxide produces 3 moles of oxygen, so
5.5 moles of Aluminium oxide will produce = 
Hence, 8.25 moles of oxygen will be produced.
