I think the number of protons in the nucleus the number of valence electrons atomic mass...
0.02 mol NaCl
Explanation:
(0.2M NaCl)×(0.10 L) = 0.02 mol NaCl
The mass/volume percent of solution is 8.69% (m/v).
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
