Answer:
1.693 atm
Explanation:
According to Boyle's Law, an inverse relationship exists between pressure and volume. ... The relationship for Boyle's Law can be expressed as follows: P1V1 = P2V2, where P1 and V1 are the initial pressure and volume values, and P2 and V2 are the values of the pressure and volume of the gas after change under a constant temperature and ideal behaviour
P1V1 = P2V2
P1 = 5.08
V1= 1.19L
P2=?
V2= 3.57L
P1V1 = P2V2
5.08x 1.19 = P2(3.57L)
6.0452/3.57 = P2 = 1.693 atm

Answer is: <span>molarity of this solution is 19,92M.
</span>m(H₂) = 0,95 g.
m(Pd) = 275 g.
d(solution) = 11,7 g/cm³.
m(solution) = 0,95 g + 275 g.
m(solution) = 275,95 g.
V(solution) = m(solution) ÷ d(solution).
V(solution) = 275,95 g ÷ 11,7 g/cm³.
V(solution) = 23,585 cm³ = 0,023585 L.
n(H₂) = m(H₂) ÷ M(H₂).
n(H₂) = 0,95 g ÷ 2,016 g/mol.
n(H₂) = 0,47 mol.
c(solution) = 0,47 mol ÷ 0,023585 L.
c(solution) = 19,92 mol/L = 19,92 M.
