Question

estimate the carge in 26grm of Na+

Answer 1

$\int\limits^a_b {x} \, dx \lim_{n \to \infty} a_n \left \{ {{y=2} \atop {x=2}} \right. \sqrt{x} \frac{x}{y} \lim_{n \to \infty} a_n \left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right] x^{123} \int\limits^a_b {x} \, dx \left \{ {{y=2} \atop {x=2}} \right.$
