This might get a little salt out but you will need to evaporate the water to completely get the salt out. Once you evaporate the water all that will be left is the salt
8 electrons are in the third level
Electrons in this level are called valence electrons
Valence electrons are used in any and all chemical reactions
percent by mass=(mass of solute/ mass of solution)*100 %
mass of solute=58.5 g
density (H₂O)=1 g/cm³*(1000 cm³/1dm³)=1000 g/dm³
mass of solvent (H₂O)=0.5 dm³ * (1000 g/dm³)=500 g
mass of solution=mass of solvent + mass of solut
mass of solution=58.5 g+500 g=558.5 g
% mass=(58.5 g/558.5 g) * 100%=10.47% of Na.
solution: 10.47% of Na.
Answer:
Molar mass = 30.026 g/mol
Explanation:
Let Molar mass be mm
mm of CH2O = 12.01 + 2(1.008) + 16.00
= 12.01 + 2.016 + 16.00 = 30.026 g/mol
