What is the molarity of a solution made by dissolving 58.8 of NaOH in 3.1 L of
solution?

The molarity of the solution is 0,47 M

Explanation:

Molarity is a concentration measurement that expresses the moles of solute (in this case NaOH) in 1 liter of solution (1000ml). First we calculate the mass of 1 mol of NaOH, to calculate the moles in 58.8 g of said compound:

Weight  1 mol NaOH= Weight Na + Weight O + Weight H=23 g + 16 g +1 g

Weight 1 mol NaOH= 40 g/mol

40 g ---1 mol NaOH

58,8g---x= (58,8g x 1 mol NaOH)/40g =1,47 mol NaOH

3,1 L solution 1,47 mol NaOH

1 L  solution x= (1 L  solution x 1,47 mol NaOH)/3,1 L solution

x= 0,47 mol NaOH ---> The molarity of the solution is 0,47 M

the millers tale is the answer.

clouds form

solid ice forms on leaves.

water droplets form on grass.
