Answer:
0.374 L
Explanation:
Step 1: Given data
Mass of silver nitrate (solute): 15.89 g
Molarity of the solution: 0.250 M
Step 2: Calculate the moles of silver nitrate
The molar mass of silver nitrate is 169.87 g/mol.
Step 3: Calculate the volume of the solution
The molarity is equal to the moles of solute divided by the liters of solution.
Due to the significant figures rules, we keep 3 significant figures.

Answer:
.0388 atm
Explanation:
Since temperature is not given , we assume that it is constant . So we can apply Boyle's law . According to it
P₁ V₁ = P₂ V₂
P₁ and V₁ are pressure and temperature initially and P₂ and V₂ are pressure and volume finally .
Putting the given values
.12 x 2.31 = 7.14 x P₂
P₂ = .12 x 2.31 / 7.14
= .0388 atm .
