If 8.5 grams of solid NaC2H3O2 are added to 100.0 mL of water, how many mL of 1.0 M HCl would need to be added to prepare a solution that has pH of 4.60. ( )40.0mL ( )48.0mL ( )60.0mL ( )75.0mL
please show work so: 1 ml stock 10 ml final -0.5 mL of stock -5 ml final volume While I have used 1:10 as a standard the same rules apply for all dilution factors. Try these problems: x 0.5 X0.5 1. You need to make a 1:25 dilution factor. If you final volume is 25 mL this means that you need_ _mL of stock and mL of solvent to make your final volume of 25 mL. 2. If you needed...
dilution If I add 25 mL of water to 125 mL of a 0.15 M NaOH solution, what will the molarity of the diluted solution be? (Your answer should be written as 0.XXX with no units) Question 2 0.2 pts If I add water to 100 mL of a 0.15 M NaOH solution until the final volume is 150 mL, what will the molarity of the diluted solution be? (Your answer should be written as 0XXX with no units) Question...
2. How many ml of 10.0M HCl do I need to add to 100ml of 1.00M NaOH to get a solution with pH = 7? 3. 75.0ml of 1.00M HCl is added to 100ml of 1.00M NaOH. what is the pH of the resulting solution? If I can get help with these two, I can do the others. Thank you. 2. (1pt) How many ml of 10.0M HCl do I need to add to 100ml of 1.00M NaOH to get...
6. (20 pts) You have a beaker containing 100 mL of water. The initial temperature of the water is 20°C. (Note: Onc ml = 1 cm'). 2. You place a piece of copper into the beakct containing. When you do, the water level increases to 110.5 m... What is the mass of the copper in grams? b. If the temperature of the water increases to 35°C, how much heat (in calories) did the copper add to the water? c. You...
#9 -/1 point If you need 19.2 grams of HCl for a reaction, and you have a 1.5 M solution of HCI, how many mL of this solution should you use? ml Evaluate If you have 0.38 x 1028 atoms of Zn, what is the mass in kilograms? Mass Zn kilograms Evaluate #5 -/1 point How many hydrogen atoms are in 0.9 kg of water? Hydrogen atoms
How much water would you need to add to 10.0 mL of 0.500 M HCl to produce a solution that is 0.200 M HCI? Just write your answer as mL with one digit beyond the decimal point. The number alone will be marked wrong.
In the lab, you weigh an empty beaker and find it to in empty beaker and find it to be 28.3456 grams. You use a volumetric pipet to transfer 50.00 ml of a sodium chloride solution in beaker and weigh the beaker again to get 80.5678 grams. You being careful to turn down the heat near the end of the process minimize the amount of 'popping' that occurs. At the v mount of 'popping' that occurs. At the very end,...
