I may be wrong worked it out in my head
1.6 mol x 42.39g/1 mol = 67.82g of LiCl.
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.
When it is filled with Helium it will expand and become more dense in the hot car. But when it becomes dense the gas molecules fly around in different directions, they collide with other objects and create pressure which can cause the balloon to pop.
