A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. (Put it in ur own words if u can) !!
.605862g H2
To find this, set up the following equation:
You're starting with 23.5 grams of potassium and you want to end up with grams of Hydrogen. To do that, you need to do a molar ratio:
23.5gK
Multiply everything on the top (23.5 x 1 x 1 x 2.016) and on the bottom (39.098 x 2 x 1).
Divide the product given from the top, 47.376, by the product from the bottom, 78.196 to get the final mass of .605862 or rounded up to .606
The reason for the molar ratio is because in the given equation, you need to take into account the needed amount of moles for each element/compound. You also cannot just go from grams to grams, you must have a conversion of moles in between just as you would for grams to molecules.
Hope this helps!
Answer: 3M
Explanation: Molarity : It is defined as the number of moles of solute present in one liter of solution.
Formula used :
where,
n = moles of solute = 0.6 moles
= volume of solution in ml= 200 ml
Now put all the given values in the formula of molarity, we get
Therefore, the molarity of solution will be 3M.
