Add a mixture of CaCO3, MgCO3 and Al2O3 weighing 0.602 g. Dissolve A in 50 ml of 0.5M HCl solution. To neutralize excess acid, 41.4 ml of 0.2M NaOH solution is required. Gaseous gas is released when A is dissolved in 93,6 ml of NaOH solution with a% concentration (d = 1,0039g / ml), then add a residue of BaCl2 solution, resulting in 0.788 g of precipitate and When boiled again, there was 0.134 more precipitate. Assuming all of these happen completely. Said a. Ingredients% of substances in A
b. Calculate a

Ineed someone to see if my answers are correct! if any are wrong let me know what the correct answers would be and how to get that answer! 1. how many moles of sodium chloride are in 28 grams od nacl? a. 265 mole naclb. 856 mole naclc. 479 mole of nacld. 1.2 mole nacl < my choice2. 734 grams of lithium sulfate (li2so4) are dissolved to make 2500 ml of solution what is rhe molaratiy? a. 2.67 mb. 4.56 mc. 3.89 m < my choiced. 1.78 m3. how many grams of cacl2 would be dissolved in 3.0 l of a 0.50 m solution of cacl2? a. 250 g cacl2 b. 166.5 g cacl2c. 113.65 g cacl2d. 98 g cacl2 < my choice4. suppose you had 58.44 g of nacl and you dissolved it in exactly 2.00 liters. the molarity if the solution would be 0.5 mtrue < my choicefalse 5. i would need 22g of naoh to make a 3.0 m solution using 250 ml of solvent.true < my choicefalse6. identify the solute: you have a .0195 m solution made from using 6.5 g of solute and 3 l of solvent. identify the solute by solving for molar weight.a. the solute is nacl because the molar weight is 58.43 g/mol < my choiceb. the solute is h2so4 because the molar weight is 98.06 g/molc. the solute is cacl2 because the molar weight is 111.11 g/mol
