The U.S. standard for arsenate in drinking water requires thatpublic water supplies must contain no greater than 10 partsper billion (ppb) arsenic. If this arsenic is present as arsenate,AsO43-, what mass of sodium arsenate would be present ina 1.00-L sample of drinking water that just meets the standard?Parts per billion is defined on a mass basis asppb =g soluteg solution * 109

nplete calculations and report answers in appropriate significant figures and units. la. In an experiment to determine the amount of acetic acid present in the given volume of vinegar, following data was obtained.The chemical reaction between acetic acid(in vinegar) and sodium hydroxide(base) is given below: CH;COOH(aq)+ NaOH(aq) → CH,COONA(aq)+ H,O(!) At equivalence point: moles of NaOH = moles of CH;COOH Molarity of NAOH solution = MNaOH = 0.100 M Complete calculations using the following data: Trial-1 Volume of Vinegar in Flask 2.00 mL Initial reading of NaOH in the buret in mL 2.05 Final reading of NaOH in the buret in mL 12.34 Total volume of NaOH used (Show calculations) in mL. Trial-1 V Initial Total Volume of NaOH solution used (in mL) =VFinal - = V NaOH Total Volume of NaOH solution used(in Liters) Moles of NaOH =(MNaOH VNaOH) Moles of Acetic acid = Mass of acetic acid in vinegar in grams (Use molar mass of acetic acid) : Volume of Vinegar used: 2.00 mL Weight/volume percent…

'(d) sodium cnionae is an ionic compound. ltcontains sodium ions, Na+ and chloride ions, CI-When molten sodium chloride is electrolysed, sodium metal and chlorine gas are formed. Describe how the sodium ions and chloride ions in solid sodium chloride are converted into sodium and chlorine by electrolysis.

How much water (in mL) should you add to 50.0 mL of 0.300 M H,SO, (ag) to get a solution of 0.130 M H2SO4 (aq)? Write just the numerical answer with proper sig figs (no units) and do not put it in scientific notation. Make sure to record and submit the full work with units and sig figs in the separate file labeled 4 work.

please help me  The aluminum in a 1.200g sample of impure ammonium aluminum sulfate was precipitatedwith aqueous ammonia as the hydrous Al2O3 · XH2O. The precipitate was filtered and ignitedat 100°C to give anhydrous Al2O3, which weighed 0.2001 g. Express the result of this analysisin terms of % Al.
