<span>1 mol mag acetate dissociates into 1 mol Mg ion and 2 mols acetate ions in water. Therefore, if 0.6 mol mg of acetate is dissolved in 0.135 literss of water, we will have 0.6/0.135 = 4.44 moles / lit Mg2+ ions and 0.6*2/0.135 = 8.88 moles / liter C2H3O2- ions.</span>
The osmium with a density of 22.6g/cm3 has a volume in cm3 of 0.965 cm3
The density formula and the procedure we will use is:
ρ = m/v
Where:
- v= volume
- ρ= density
- m= mass
Information about the problem:
Applying the density formula and isolating the volume (v), we get:
ρ = m/v
v = m / ρ
v = 21.8 g / 22.6g/cm3
v = 0.965 cm3
<h3>What is density?</h3>
It is a physical quantity that expresses the ratio of the body mass to the volume it occupies.

This follows Boyles law which relates pressure and volume. The law states that pressure is inversely proportional to volume at a constant temperature.
PV = k
where k is a constant.
At two instances ;
P1V1 = P2V2
where parameters for the 1st instance is on the left and parameters for the second instance is on the right.
37.5 kPa x 41.3 L = 13.8 kPa x V2
V2 = 37.5 x 41.3 / 13.8
V2 = 112.23 L
At the new pressure gas will take up a volume of 112.23 L
