I want to say Neutrons.
Hope this helps!
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:
Explanation:
Hello!
In this case, since the sulfuric acid and sodium hydroxide react in a 1:2 mole ratio, given the reaction, we realize they have the following mole ratio at the equivalence point:
Which in terms of concentrations and volumes is:
Thus, we can plug in the volume and concentration of acid to find the moles of base:
Best regards!
