When the volume and concentration of a base that completely neutralizes an acid is known, you can determine the concentration of

the acid due to at the point of neutralization, the number of moles of acid equals the number of moles of base.
why does this happen? (btw this is describing titration) the criteria for the answer is
"Try to answer why the results occurred. If you are in chemistry, what is happening at the molecular level with bonding, electrons, etc. " WILL MARK BRAINLIEST!!!!

Magnesium reacts with Oxygen gas forming Magnesium oxide as shown;
LuckyWell [14K]
Molar mass:

O2 = 16 x 2 = 32.0 g/mol              Mg = 24 g/mol

<span>2 Mg(s) + O2(g) --->2 MgO(s) 
</span>
2 x 24.0 g Mg -------------> 32 g O2
5.00 g Mg -----------------> ( mass of O2)

mass of O2 = 5.00 x 32 / 2 x 24.0

mass of O2 = 160 / 48

= 3.33 g of O2

hope this helps!

What volume of water has the same mass as 9.0m3 of ethyl alcohol?
Triss [41]
This question requires the knowledge of density. 

The density of ethyl alcohol = 789 kg m⁻³
The density of water = 1000 kg m⁻³

Density = Mass / Volume 

By applying ethyl alcohol,
    789 kg m⁻³ = Mass / 0.9 m³
         Mass     = 710.1 kg
hence the mass of 0.9 m³ ethyl alcohol is 710.1 kg.

Then by applying water,
     1000 kg m⁻³ = 710.1 kg / Volume
      Volume        = 0.7101 m³
                          = 0.7 m³
hence the equal water volume is 0.7 m³
