Answer: 0.4M
Explanation:
Given that,
Amount of moles of NaOH (n) = ?
Mass of NaOH in grams = 40.0g
For molar mass of NaOH, use the atomic masses: Na = 23g; O = 16g; H = 1g
NaOH = (23g + 16g + 1g)
= 40g/mol
Since, n = mass in grams / molar mass
n = 40.0g / 40.0g/mol
n = 1 mole
Volume of NaOH solution (v) = 2.5 L
Concentration of NaOH solution (c) = ?
Since concentration (c) is obtained by dividing the amount of solute dissolved by the volume of solvent, hence
c = n / v
c = 1 mole / 2.5 L
c = 0.4 mol/L (Concentration in mol/L is the same as Molarity, M)
Thus, the concentration of a solution of a 40.0 g of NaOH in 2.5 L of solution is 0.4 mol/L or 0.4M
Since the atoms or molecules in a solid do not translate hence, the structures of solids usually described in terms of the positions of the constituent atoms rather than their motion.
<h3>States of matter</h3>
There are three state of matter which are;
In a solid, atoms or molecules retain their positions and do not translate, hence, the structure of atoms or molecules are most important in determining the structure of a solid.
Also, the fact that the atoms or molecules in a solid can only vibrate or rotate explains why the structures of solids usually described in terms of the positions of the constituent atoms rather than their motion.
