Solution:
2 short-ton = ? metric-ton
The conversion path will be:
short-ton→metric-ton
2 short-ton
= 2 short-ton * $ { \frac { 1\;metric\;ton } { 1.12\;short\;ton } } $
= 2 * $ { \frac { 1 } { 1.12 } } $ metric-ton
= 2 * 0.8928571428571428 metric-ton
= 1.7857142857142856 metric-ton

Van der waals gases
Express $V$ as a function of $n$, $P$, $T$
$V$ = Volume of ideal gas
$n$ = Number of moles of ideal gas
$P$ = External pressure on of ideal gas
$T$ = Temperature of ideal gas
$R$ = Ideal Gas Constant
$a$ = A is a constant whose value depends on the gas
$b$ = The volume that is occupied by one mole of the molecules
Use constant = $\displaystyle R$
Answer:
$\displaystyle V - n 1 \propto \frac{T V^{2} n}{P V^{2} + n^{2}}$
$\displaystyle \implies V - n b = R T n \left(P + \frac{n^{2} a}{V^{2}}\right)^{-1}$
$\displaystyle \implies \left(P + \frac{n^{2} a}{V^{2}}\right) \left(V - n b\right) = n R T$
$\displaystyle \implies V - n b = R T n \left(P + \frac{n^{2} a}{V^{2}}\right)^{-1}$
$\displaystyle \implies \left(P + \frac{n^{2} a}{V^{2}}\right) \left(V - n b\right) = n R T$
Solution:
Let:
$V$ = Volume of ideal gas
$n$ = Number of moles of ideal gas
$P$ = External pressure on of ideal gas
$T$ = Temperature of ideal gas
$R$ = Ideal Gas Constant
$a$ = A is a constant whose value depends on the gas
$b$ = The volume that is occupied by one mole of the molecules
The relation between variables:
$\displaystyle V - n 1 \propto \frac{V^{2} n}{V^{2} + n^{2}}$
$\displaystyle V - 1^{2} \propto \frac{V^{2}}{P V^{2} + 1}$
$\displaystyle V - 1^{2} \propto \frac{T V^{2}}{V^{2} + 1}$
$\displaystyle \implies V - n 1 \propto \frac{T V^{2} n}{P V^{2} + n^{2}}$
$\displaystyle
\implies V - n b = R T n \left(P + \frac{n^{2} a}{V^{2}}\right)^{-1}
\qquad \text{as constant} = R

Gram AMU Conversion
Find $n$
Where:
$\displaystyle
m $ = mass of Neodymium atom in gram = $\displaystyle
2884.84000000000 \; gram $
$\displaystyle
M $ = Mass of one mole of Neodymium atom = $\displaystyle
144.242000000000 \; \frac{gram}{mole} $
$\displaystyle
n $ = Number of moles of Neodymium atom ($\frac{m}{M}$)
$\displaystyle
N $ = atomic mass unit (AMU) per gram = $\displaystyle
6.02214076e+23 \; \frac{AMU}{gram} $
$\displaystyle
q $ = mass of Neodymium atom in atomic mass unit (AMU) = $\displaystyle
1.73729125500784E+27 \; AMU $
Answer:
$\displaystyle 20.0\;mole$
Solution:
Let:
$q$ = mass of Neodymium atom in atomic mass unit (AMU)
$m$ = mass of Neodymium atom in gram
$M$ = Mass of one mole of Neodymium atom
$n$ = Number of moles of Neodymium atom ($\frac{m}{M}$)
$N$ = atomic mass unit (AMU) per gram
The relation between variables:
$\displaystyle q \propto n$
$\displaystyle q \propto M$
$\displaystyle \implies q \propto M n$
$\displaystyle
\implies q = N M n
\qquad \text{as constant} = N
$
Substituting values:
$\displaystyle \implies \left(1.73729125500784E+27\;AMU\right) = \left(6.02214076e+23\;\frac{AMU}{gram}\right) \left(144.242000000000\;\frac{gram}{mole}\right) n$
Hint:
Molar mass of Neodymium atom
= 144.242 $\mathtt{\text{AMU}}$
= 144.242000000000 $\mathtt{\text{AMU}}$
Simplify the equation:
$\displaystyle \implies 1.73729125500784\;\cdot\;10^{27}\;AMU\;=\;\frac{8.6864562750392\;\cdot\;10^{25}\;AMU\;n}{mole}$
Solve for $n$:
$\displaystyle \implies n =
$ $\displaystyle 20.0\;mole$
$q$ = mass of Neodymium atom in atomic mass unit (AMU)
$m$ = mass of Neodymium atom in gram
$M$ = Mass of one mole of Neodymium atom
$n$ = Number of moles of Neodymium atom ($\frac{m}{M}$)
$N$ = atomic mass unit (AMU) per gram
The relation between variables:
$\displaystyle q \propto n$
$\displaystyle q \propto M$
$\displaystyle \implies q \propto M n$
$\displaystyle
\implies q = N M n
\qquad \text{as constant} = N
$
Substituting values:
$\displaystyle \implies \left(1.73729125500784E+27\;AMU\right) = \left(6.02214076e+23\;\frac{AMU}{gram}\right) \left(144.242000000000\;\frac{gram}{mole}\right) n$
Hint:
Molar mass of Neodymium atom
= 144.242 $\mathtt{\text{AMU}}$
= 144.242000000000 $\mathtt{\text{AMU}}$
Simplify the equation:
$\displaystyle \implies 1.73729125500784\;\cdot\;10^{27}\;AMU\;=\;\frac{8.6864562750392\;\cdot\;10^{25}\;AMU\;n}{mole}$
Solve for $n$:
$\displaystyle \implies n =
$ $\displaystyle 20.0\;mole$
