Determine the number of neutrons in an atom U-233.

alexdok [17]

We Know, Atomic number of Uranium = 92
Molar mass in given species = 233

Now, Molar mass = Number of Protons + Number of Neutrons
233 = 92 + x
x = 233 - 92
x = 141

So, your final answer is 141

Hope this helps!

Equal volumes of hydrogen and helium gas are at the same pressure. The atomic mass of helium is four times that of hydrogen. If

OverLord2011 [107]

Answer:

The ratio of the temperature of helium to that of hydrogen gas is 2:1.

Explanation:

Atomic mass of hydrogen = M

Temperature of hydrogen gas =T

Pressure of the hydrogen gas = P

Mass of the hydrogen gas = m

Moles of the hydrogen gas = $n=\frac{m}{2M}$

Volume of the hydrogen gas = V

Using an ideal gas equation:

$PV=nRT=PV=\frac{mRT}{M}$ ...(1)

Temperature of helium gas =T'

Pressure of the helium gas = P'= P

Mass of the helium gas = m' =m

Moles of the helium gas = $n'=\frac{m}{M'}=\frac{m}{4M}$

Volume of the helium gas = V' = V

Using an ideal gas equation:

$P'V'=n'RT'=\frac{mRT'}{4M}$ ...(2)

Divide (2) by (1)

$\frac{P'V'}{PV}=\frac{\frac{mRT'}{4M}}{\frac{mRT}{2M}}$

$\frac{T'}{T}=\frac{2}{1}$

The ratio of the temperature of helium to that of hydrogen gas is 2:1.
