Suppose you wanted to make an aqueous solution of sodium hydroxide that is 1.8 m. you want to make 250 ml of the solution. how many grams of sodium hydroxide are needed to make this solution? note which type of calculation you need to perform, and then perform the calculation.

Answer : The mass of sodium hydroxide is, 18 grams

Explanation : Given,

Molarity of sodium hydroxide = 1.8 M  = 1.8 mole/L

Molar mass of sodium hydroxide = 40 g/mole

Volume of solution = 250 ml

Molarity : It is defined as the number of moles of solute present in one liter of solution.

In this question, the solute is sodium hydroxide.

Formula used :

Now put all the given values in this formula, we get the  mass of sodium hydroxide.

Therefore, the mass of sodium hydroxide is, 18 grams

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
