Calculate the no. of atoms in 23 gm of sodium?

1.	Calculate the no. of atoms in 23 gm of sodium?
Answer» $\huge\mathfrak{Solution :}$ GIVEN Mass of Sodium (Na) = 23 G Molar Mass of Sodium (Na) = 23 g $\textbf{No. of <klux>MOLES</klux> = Given mass / Molar}$ $\textbf{mass}$ •°• No. of moles of Sodium = 23 / 23 = 1 mole As we know, 1 mole of any substance contains => $6.022 \times {10}^{23}$ Atoms / MOLECULES / ions. $\textbf{Hence,}$ 23 g of Sodium contains $6.022 \times {10}^{23}$ Atoms. $\huge\mathbb{Hope \ this \ helps.}$
