Solution :
Molecular mass of NaOH is 23 g/mol .
So, number of moles of NaOH is given by :

Now, we know molarity is given by :


Hence, this is the required solution.
Instead, they are created when magma cools and hardens —> the temperature contributes as the magma would be at extreme heat while it need a cooler temperature to harden and mold
Hi! Well the formula of kinetic energy is Ke = 0.5 x M x V^2
0.5 x 0.5 x 10^2
0.25 x 20
5 J (joule)
Explanation:
vertical columns and horizontal rows, hope it helps
