Answer:
P₂ = 2.88 atm
Explanation:
Given data:
Initial volume of gas = 1.8 L
Final volume = 750 mL
Initial pressure = 17.5 Psi
Final pressure = ?
Solution:
We will convert the units first:
Initial pressure = 17.5 /14.696 = 1.2 atm
Final volume = 750 mL ×1L/1000L = 0.75 L
The given problem will be solved through the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
1.2 atm × 1.8 L = P₂ ×0.75 L
P₂ = 2.16 atm. L/ 0.75 L
P₂ = 2.88 atm
The chemical formula of manganese (Il) phosphate is Mn3(PO4)2, which is option 2.
<h3>What is chemical formula?</h3>
The chemical formula of a compound is the notation indicating the number of atoms of each element present in a compound.
The chemical formula of a compound tells us the type of elements in the compound, the number atoms of each element in the compound and in what proportion these elements are present.
According to this question, manganese II phosphate has the chemical formula of Mn3(PO4)2.
This chemical formula shows that it posseses the following:
- 3 manganese atoms
- 2 phosphorus atoms
- 8 oxygen atoms

Viscosity refers to a fuilds resistance to flow.
EX: Honey have higher viscosity than water.
<span>Atoms move at different speeds depending on whether they are in liquids or solids </span><span>because the atoms or particles in solids are closely bonded while they are loosely bonded in liquids.
</span><span>
</span><span>
</span><span>The attractive forces between the particles are so high that they remain in fixed positions. The particles, then, cannot slip over the neighbors particles. They can only vibrate. That is why solids have definite form and volume.</span><span />
<span>That the particles in liquids are loosely bonded means that the attractive forces are less compared with solids. Then the partilces can move and pass each other. They are not in fixed arrangements any more. Yet the particles are attracted to each other, so they have definite volume, although they take the form of the vessel, and they can flow.
