Cerebrum is the part of the brain that we use for imagination, thinking, judgement etc. It is also the largest part of the brain

Cerebellum is in charge of stuff like the spinal cord

and the brain stem is the part of the brain that helps us move. (if you watch the walking dead in one of the episodes it teaches this xD)

hope this helped (:

Solutions of hydrogen in palladium may be formed by exposing Pd metal to H gas. The concentration of hydrogen in the palladium d

Juliette [100K]

Explanation:

Mass of solution , m= 0.94 g + 215 g = 215.94 g

Volume of the solution = V

Density of solution = d = $10.8 g/cm^3$

$V=\frac{m}{d}=\frac{215.94 g}{10.8 g/cm^3}=19.99 cm^3=19.99 mL$

$1 cm^3=1 mL$

$1 mL=0.001 L$

$V=0.01999 L$

Moles of hydrogen = $\frac{0.94 g}{2 g/mol}=0.47 mol$

Molarity of hydrogen gas:

$Molarity=\frac{Moles}{\text{Volume of solution (L)}}$

$=\frac{0.47 mol}{0.01999 L}=0.02351 mol/L$

Molality of hydrogen gas :

Mass of solvent or here it is palladium = 215 g =0.215 kg (1 g = 0.001 kg)

$Molality=\frac{Moles}{\text{Mass of solvent(kg)}}$

$=\frac{0.47}{0.215 kg}=2.1860 mol/kg$

Mass percentage of hydrogen is solution :

$\frac{\text{Mass of hydrogen}}{\text{Mass of solution}}\times 100$

$=\frac{0.94 g}{215.94 g}\times 100=0.435\%$
