P₁ = 0.90 atm
V₁ = 50.0 mL
T₁ = 298 K
P₂ = 1 atm
T₂ = 273 K
V₂ = P₁ x V₁ x T₂ / T₁ x P₂
V₂ = 0.90 x 50.0 x 273 / 298 x 1
V₂ = 12285 / 298
V₂ = 41 mL

Nuclear energy originates from the splitting of uranium atoms – a process called fission. This generates heat to produce steam, which is used by a turbine generator to generate electricity. Although renewable energy sources, like wind and solar power, are
important resources for a country’s energy mix, only nuclear power is
capable of producing large amounts of electricity 24 hours a day, 365
days a year.
For safety precaution which regards to employees, several federal agencies—the US Nuclear Regulatory Commission (NRC),
the U.S. Environmental Protection Agency and the U.S. departments of
Energy and Transportation—establish radiation protection regulations for
U.S. nuclear plants based on internationally recognized scientific
studies.
For the safety precaution of power plants itself, The NRC monitors plant performance according to three strategic areas:
reactor safety, radiation safety and security.

The answer to your question is:
1.- 320 ml
2.- 0.63 M
Explanation:
Data
V = ? AlBr₃ = 0.157 M
mass = 13.4 g
Process
MW ALBr₃ = 27 + (80x3) = 267 g
267 g -------------------- 1 mol
13.4 g ------------------ x
x = (13.4 x 1) / 267
x = 0.05 moles
Volume = 0.05/ 0.157
= 0.320 l or 320 ml
2.-
NaNO₃ mass = 20.2 g
V = 375 ml
Molarity = ?
MW = 23 + 14 + 48 = 85g of NaNO₃
85 g of NaNO₃ ----------------- 1 mol
20.2 g ----------------- x
x = (20.2 x 1) / 85
x = 0.24 mol
Molarity = 0.24 / 0.375
= 0.63
