How many grams of Al(no2)3 should be added to 1.3L of water to prepare a 2.0M solution

429 grams of  should be added to 1.3 L of water to prepare 2.0 M solution

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

where,

n = moles of solute =  

= volume of solution in Liters  

Now put all the given values in the formula of molarity, we get

Therefore, 429 grams of  should be added to 1.3 L of water to prepare 2.0 M solution

u i forgot the answer?

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.
