The Mass number is 65, Copper-65
To find the mass number you add the number of protons to the number of neutrons.
Density = mass / volume
We know the density and the mass of magnesium.
First, convert 1.35 kg into g:
1 kg = 1000 g
1.35 kg = 1350 g
Now, substitute the values for density and mass into the equation.
1.74 = 1350 / volume ---> Multiply both sides by 'volume':
1.74 x volume = 1350 ---> Divide both sides by 1.74 to find the volume:
volume = 775.86 g/cm^3 (2.d.p.)
Answer: The value of acid ionization constant for acetic acid is
Explanation:
cM 0 0
So dissociation constant will be:
Give c= 0.85 M and = 2.4
Putting in the values we get:
Thus the value of acid ionization constant for acetic acid is
