How many grams of K2SO4 would you need to prepare 1500 g of 5.0% K2SO4 (m/m) solution?
1500 * 0.05 = 75
75g of K2SO4 to make 1500g of a 5% solution.
Well, if you're looking to prepare a 5.0% K2SO4 solution, you'll need a little bit of math and a whole lot of K2SO4. Let me put on my clown nose and calculate it for you!
First, we need to find out how much K2SO4 is actually in the solution. Since it's a 5.0% solution, that means 5% of the 1500 g will be K2SO4. So, 5% of 1500 g is 75 g.
This means you'll need 75 grams of K2SO4 to prepare your 1500 g of 5.0% K2SO4 solution. Who knew math could be so salty?
To calculate the amount of K2SO4 needed to prepare a 5.0% (m/m) solution, we first need to determine the mass of K2SO4 in the solution.
The term "5.0% (m/m)" means that the mass of K2SO4 is 5.0% of the total mass of the solution.
Step 1: Calculate the mass of K2SO4 in the solution.
Total mass of the solution = 1500 g
Mass percent of K2SO4 = 5% = 5/100 = 0.05
Mass of K2SO4 = (Mass percent of K2SO4) x (Total mass of the solution)
= 0.05 x 1500 g
= 75 g
Therefore, you would need 75 grams of K2SO4 to prepare 1500 g of a 5.0% K2SO4 (m/m) solution.
To determine the number of grams of K2SO4 needed to prepare a 5.0% (m/m) solution, we need to understand that the percentage by mass (% m/m) is calculated as:
% m/m = (mass of solute / mass of solution) × 100
In this case, we know the mass of the solution is 1500 g and the desired percentage of K2SO4 is 5.0% (m/m).
Step 1: Calculate the mass of K2SO4 in the solution.
% m/m = (mass of K2SO4 / mass of solution) × 100
Rearranging the equation, we get:
mass of K2SO4 = (mass of solution × % m/m) / 100
Substituting the values:
mass of K2SO4 = (1500 g × 5.0%) / 100
Step 2: Calculate the mass of K2SO4.
mass of K2SO4 = (1500 g × 5.0) / 100
mass of K2SO4 = 75 g
Therefore, you would need 75 grams of K2SO4 to prepare 1500 grams of a 5.0% (m/m) K2SO4 solution.
