PV = nRT (where P = pressure; V = volume; n = number of moles; R = gas constant; T = Temperature)
Moles of H₂ = mass of H₂ ÷ molar mass of H₂
= 6.0 g ÷ 2 g/mol
= 3.0 mol
To get the answer in atmospheres, let's convert C to K
25 °C ≡ 298 K
Now, based on the formula above
P = (nRT) ÷ V
P = (3.0 mol × (0.082 L · atm/mol · K) × 298 K) ÷ 73 L
≈ 1 .004 atm
A) LITHIUM is the least reactive alkali metal
B) FRANCIUM is the most reactive alkali metal
C) BERYLLIUM is the least reactive alkaline earth metal
D) RADIUM is the most reactive alkaline earth metal
E) TENNESSINE is the most reactive halogen
For E it might also be Astatine because Tennessine is a fairly new
