You just have to remember the formula of Molarity which i have written in the first pic and you have to know what each symbol indicate.
Now just put the values in formula and get answer.
Do give a thumbs up.

Now, you start to prepare a sodium bicarbonate solution and you can only find 1.75M NaHCO, (liquid; mw=84.07) solution in the cabinet to use. Your instructions state you need 500ml of 75mM NaHCO3. 7. Identify the final concentration and final volume of the solution you are making, the initial concentration of the solute source, write out the formula, and then complete the math. How much of this solution and solvent from the cabinet should you use to prepare this solution?...
PLEASE SHOW WORK AND BE CLEAR!!!! 1. Calculate the following: How do you prepare 75 mL of 2% ferric chloride from a 10% solution? If you only have ferric chloride crystals, how much do you need? mL H20 mL 8 Esch How many mL of an 11% solution will 300 g of sodium chloride make? 8.25 mL hydrochloric acid diluted to 450 mL is what percent solution? 13.5 g of potassium dichromate will make how many mL of a 5%...
2. Show all work (2 pts), units on every number that has units (1 pt), and the correct answer (2 pt) A relatively old container of NaOH (MW: 39.997 g/mol) pellets is used to make a -0.1 M solution. 2.00 g of the solid NaOH is weighed out, dissolved into water and diluted to a total solution volume of 500.0 mL. The NaOH solution is standardized using KHP (204.22 g/mol). It takes 15.90 mL of the NaOH solution to titrate...

This lab illustrates how supersaturated solutions are prepared, and the process of crystallization. This lab can be done with a number of different salts. You will need to allow your solutions to sit for at least three weeks. This is one way to make rock candy. Be SURE to start this lab with plenty of time to finish. Materials -string -pencils -glass drink bottles -various salts (choose from the following list.) -table salt, sodium chloride -alum -baking soda -copper sulfate...
Question 11 of 19 1 Points Which pair of compounds is most likely to be completely miscible with one another? The term "miscible" means soluble in all proportions -- no matter how much solute is added to the solvent, a homogeneous mixture (a solution) will result. A. hexane (CH2) and water B. methanol (CH,OH) and water C. table sugar (sucrose, C12H3201) and water D. sodium chloride (NaCl) and water Reset Selection
When chemists work with solid materials, we simply weigh out amounts of solid reagents and calculate mole amounts when thinking about stoichiometry. However, when we dissolve a solid (also known as a solute) in a solvent to form a solution, the solute becomes evenly distributed throughout the solution and we need to know how many moles of solute are present in a particular volume of solution. pt. 1 A solution is created by dissolving 10.0 grams of ammonium chloride in...
please help me with this THANK YOU!!! 1. You are trying to make a homemade electrolyte energy drink similar to Gatorade. Gatorade contains 270. mg of sodium chloride and 34.Og of sugars per 591 mL (20.0 oz.) bottle. You have a solution of NaCl that is 5 wt% sodium chloride and the rest water. You have a solution of sucrose (common table sugar) that is 10 wt% sucrose and the rest water. You have as much extra water as needed....
