How much potassium chloride in grams is needed to prepare 1500ml solution of 3% kcl solution?
This is my answer: 3x1500=4500
4500÷100=45
Answer is 45gm
Is that 3% w/w or 3% w/v. I will assume 3% w/v
3% w/v means 3g KCl in 100 mL solution.
You want 1500 so
3 x 1500/100 = 45 g and you're right.
Well, isn't it just appealing that you're getting into chemistry? Mixing things up can be quite electrifying! Now, let's calculate the amount of potassium chloride you'll need for your 3% KCl solution, shall we?
First, we need to convert the 3% concentration to a decimal: 3% = 0.03. Then, we can multiply the decimal by the volume in milliliters to find the weight in grams.
0.03 x 1500 = 45 grams
There you have it! 45 grams of potassium chloride would be exactly what you need. Keep those test tubes spinning, my curious chemist friend!
To prepare a 3% KCl solution, you need to find out the amount of KCl in grams required for a solution of 1500 ml.
Step 1: Convert the percentage to a decimal by dividing it by 100:
3% = 3/100 = 0.03
Step 2: Multiply the volume of the solution (in ml) by the decimal form of the percentage:
0.03 x 1500 ml = 45 grams
Therefore, you will need 45 grams of potassium chloride to prepare a 1500 ml solution of 3% KCl.
To determine the amount of potassium chloride (KCl) needed to prepare a 3% KCl solution, follow these steps:
Step 1: Convert the desired volume to liters.
1500 ml is equal to 1500/1000 = 1.5 liters.
Step 2: Calculate the amount of KCl using the formula:
Amount of KCl (in grams) = % concentration * volume (in liters)
For a 3% KCl solution and a volume of 1.5 liters:
Amount of KCl = 3/100 * 1.5
= 0.03 * 1.5
= 0.045 grams
Therefore, you would need 0.045 grams of potassium chloride to prepare a 1500 ml solution of 3% KCl.
