It is a solution whose strength and quantity are given .
To make a 7.5% solution of sodium carbonate in water, add 7.5 grams of sodium carbonate to 100 mL of water and stir until the sodium carbonate is completely dissolved. This will give you a 7.5% (w/v) solution of sodium carbonate.
The solubility of sodium carbonate in water is around 22 g/100 mL of water at room temperature (20°C).
Molarity is moles per litre. You need to divide the moles by 1500 and multiply by 1000. 5.6/1500*1000 is 3.73333 molar.
When sodium carbonate (washing soda) and vinegar are combined, a chemical reaction occurs, leading to the formation of carbon dioxide gas, water, and sodium acetate. The reaction is exothermic, meaning it releases heat. This reaction can be used for various purposes such as cleaning or as a demonstration of chemical reactions.
To prepare a 0.0500 M sodium carbonate solution, you would need to accurately weigh out the required amount of anhydrous sodium carbonate (Na2CO3), dissolve it in a known volume of water, and then dilute to the appropriate final volume while ensuring thorough mixing to achieve homogeneity. Make sure to use appropriate glassware and techniques to maintain accuracy.

Does not convert; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
Firstly, they'll react each other forming sodium hydrogen carbonate and sodium chloride. If there is excess HCl, the sodium hydrogen carbonate would further react till sodium chloride and evolve carbon dioxide.
1) 0.10 mol of solid sodium hydrogen carbonate and 0.20 mol of solid sodium carbonate are dissolved in the same beaker of water, transferred to a volumetric flask and made to 250.0 mL. The Ka for HCO3 - is 4.7 x 10-11. a) What is the pH of the resulting buffer? b) What is the pH of solution after 20.00 mL of 0.050 mol L-1 hydrochloric acid solution is added to 25.00 mL of the original solution? c)What is the pH of the resulting buffer after 0.040 g of solid sodium hydroxide is added to 25.00 mL of the original solution? 2) Plan how you would make 100.0 mL of a buffer solution with a pH of 10.80 to be made using only sodium carbonate, sodium hydrogen carbonate and water.Youshould specify the amounts of sodium carbonate and sodium hydrogen carbonate that you would use. ( the ration acid to base is 3:1)
The solubility of sodium carbonate in water is around 22 g/100 mL of water at room temperature (20°C).
Molarity = moles of solute/Liters of solution ( 1500 mL = 1.5 Liters ) Molarity = 0.800 moles NaOH/1.5 Liters = 0.533 M sodium hydroxide ...
Mix 100 mL of a 1 N solution with 900 mL of distilled water.
Molarity = moles of solute/Liters of solution ( 1500 mL = 1.5 Liters ) Molarity = 0.800 moles NaOH/1.5 Liters = 0.533 M sodium hydroxide ...
Yes, NaCH3COO (sodium acetate) is soluble in water as are all sodium compounds.
Molarity is moles per litre. You need to divide the moles by 1500 and multiply by 1000. 5.6/1500*1000 is 3.73333 molar.
first of all, let's find the molecular formula for the two substances: Na2(CO3) and Na(HCO3). sodium carbonate has two Na atoms in each molecule and sodium bicarbonate has only one. now let's find the number of moles of sodium carbonate and sodium bicarbonate we have: 2.5M * .04L = .1mol 1M * .03L = .03mol we now know that there are .2mol (.1*2) of Na in sodium carbonate because there's two sodium ions in each sodium carbonate. And we know that there's 1 Na ion in each sodium bicarbonate, so we know it's just .03 mol Na in sodium bicarbonate. add those up: .2mol+.03mol = .23mol Na since Molar = mol/volume, we can find the volume of the whole solution: 30mL + 40mL=70mL or .07L .23mol/.07L is 3.29M
