Density can be calculated using the following rule:
density=mass/volume
therefore,
volume=mass/density
we have mass=0.451g and density=0.824g/ml
substituting in the above equation, we can calculate the volume as follows:
volume = 0.451/0.824 = 0.547 ml
Electrons and protons because they are essentially always the same
I believe the correct answer from the choices listed above is the fifth option. Of the following , the strong electrolyte would be NH4NO3. NH4NO3<span> is a salt and completely dissociates in aqueous solution. Hope this answers the question. Have a nice day.</span>
1.123 nano-grams is your answer, do you understand now gimme dat 5 star and brainiest
Answer:
56.0 g
Explanation:
Calculation of the moles of 
as:-
Mass = 85.0 g
Molar mass of = 162.2 g/mol
The formula for the calculation of moles is shown below:
Thus,
According to the reaction:-
1 mole of on reaction forms 1 mole of 
Also,
0.52404 mole of on reaction forms 0.52404 mole of
Moles of = 0.52404 moles
Molar mass of = 106.867 g/mol
Mass = Moles*Molar mass = 
= 56.0 g
