Consider $100$ mol of helium gas at a certain pressure $(P),$ volume $(V),$ and temperature $(T).$ Assuming that the ideal gas law applies, can you compute one of the $3$ quantities given the other two?

Recall that, with $SI$ units, the ideal gas law is given by:Write a function that takes a MATLAB variable, x$,$ which is always a $3-$element row vector containing the values of P$,$V$,$T in that order. However, exactly one of these values will be NaN, which you must solve using the ideal gas law equation above, given the other two values. All inputs are given in SI units, hence, you can use the given value of R above. Note that n$=100$ mol. You are ensured that P$,$ V$,$ and$/$or T are floating$-$point numbers with $2$ decimal places that satisfy the following constraints:

$1{10}^{5}P3{10}^5$

$1V10$

$300T500$

Output the value of the missing quantity rounded to $2$ decimal places, followed by a space, and then the correct units, either $Pa,m^3,$ or K$.$ For this, you can use sprintf. See sample test cases:
