(15 points) Solution Molarity (M) Calculation: 35 mt aqueous solution containing 2.6 grams of KCI please show work 13) How many grams of glucose are needed to prepare 400 mL of a 2.0%(m/v) (3 points) 9. What volume in liters is needed of a 3.5M NaOH solution to obtain 1.8moles of NaOH?(M.w of NaOH = 40 gram/mole). Suppose V1 liter 15 % W/V NaOH and V1 liter 5 % W/V NaOH solution is requirecl to pre pece one litev 2 M NaOH solution.OK you want to know gramwt of NaOH for 1.25M concentration of 35 mL volume OK M=1.25 molecular wt=40 formula is M=gmwt A 38.0mL solution 0.026M solution of HCl reacts with a 0.032M NaOH. a)calculate the number of moles of HCl originally present. b)how many moles of NaOH are needed to...a 15.00mL sample of NaOH was titrated to the stoichiometric point with 17.40mL of 0.2340M HCl. a) what is the molar concentration of To standardize a solution of NaOH, one uses a primary standard called potassium hydrogen phthalate (KHP). It is a monoprotic acid. It has a molar mass of 204.33g/mol.Answer. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.
What would be the volume of 15% w/v and 5% w/v NaOH solution...
...Volume of NaOH solution used (mL) 25.10 (Final reading Initial reading) 24.95 25.15 Titration 1 Discussion: Titration is the quantitative measurement of an unknown solution by reacting it with a Furthermore, addition of NaOH might be used because the initial colour change might be too minor to...Ok so I have no idea how to do this problem. I attempted it a few times and this is what I got: 1.52 g/mL = 275/v = 180.92 x 2 = 361.8 which rounds to 362. That makes sense now that I know the problems means that NaOH is 50.0% of the solution. I don't like how they are worded because the worksheet is...Transcribed Image Text from this Question. What volume (mL) of a 15% (m/v) NaOH solution contains 120 g NaOH?Answer:8.0*10^2Explanation:What volume (in milliliters) of a 15% (m/v) NaOH solution contains 120 g NaOH? For 15% (m/v), the conversion factor For 15% (m/v), the conversion factor can be 15%/100 mL or 100 mL/15%. In this case, 100 mL/15% is used because we need mL as our final expression.
How many grams of NaOH are required to prepare 350mL of...
KHP reacts with NaOH in one million:one million molar ratio Molar mass KHP = 204.2g/mol 2.042g KHP = 2.042/204.2 = 0.01 mol HKP The 20mL of NaOH contained 0.01mol NaOH Mol NaOH in 1000mL = .01/20*one thousand = 0.5 Determine the volume of a solid gold thing which weights 500 grams?Find volume of NaOH needed to neutralize the solution. Relate moles of H3PO4 with the moles of NaOH with the helps of coefficients in front of NaOH and H3PO4 seen in balanced equations. moles ↔ Litre use definition of molarity (moles/litrs). Start with what is given for H3PO4. 0.015 lit of H3PO4 x...15.1 Solubility 15.2 Solution Composition: An Introduction 15.3 Solution Composition: Mass Percent 15.4 Solution Composition: Molarity 15.5 Dilution 15.6 Stoichiometry Of Solution Reactions 15.7 Neutralization What volume of 0.104 M H2SO4is required to neutralize 15.2 mL of 0.152 M NaOH?Studyres contains millions of educational documents, questions and answers, notes about the course, tutoring questions, cards and course recommendations that will help you learn and learn. What volume (mL) of a 15% (m/v) NaOH solution contains 120 g NaOH?Reacting mass chemical calculations - reacting masses, equations, volumes and concentrations - volumetric (a) What is the concentration of a salt solution if you dissolve 10g of sodium chloride in 250 cm3 of water?
