By sugar I assume you mean sucrose. 15g in 200ml is the same as 75g in a litre. 75 / molecular weight of sucrose (342.3g/mol) is 0.2191 molar.


Molarity = moles of solute/liters of solution M = 10 mol NaOH/1 liter = 10 M -log(10 M) = -1 14 - (-1) = 15 pH sodium hydroxide


15g in 100L is 0.15g/ litre. The molecular weight of NaOH is 40g/mol. 0.15/40 is .00375 molar.


15 grams sugar per liter is the concentration, in terms of mass per volume. To express the concentration in molarity (assuming the sugar is sucrose): 15 g sucrose * (1 mole sucrose / 342 g sucrose) / 1 L = 0.0439 M aqueous sucrose


molarity = number of moles of solute / volume of solution number of moles of solute = molarity x volume of solution number of moles of solute = 12 (mole/L) x 15/1000 (L) number of moles of solute = 0.18 mole



2.5 0.05 L (50 mL) * 15 Mol/L= 300 Mol/L * X litres (0.05 L * 15 Mol/L) / 300 Mol/L = 0.0025 L or 2.5 mL


Molarity of a solution is the number of moles of the solute divided by the volume of the solution (in liters). If 750 ml of 20M HCl is mixed with 250 ml of 60M HCl, we first find the total number of moles of HCl in our new solution. Using that same formula, M=moles/V, we cansee that moles=MV. In the first solution we have (20M)(0.750L) = 15 moles. In the second, (60M)(0.250L) = 15 moles, so we have a total of 30 moles in our new solution, which also has a volume of 750mL + 250mL = 1L. The molarity of the new solution is 30 moles/1L = 30M


molar mass = mass / moles Molarity = mole of solute/ L of solution Therefore, mole of solute = 0.1008 M * 0.0150 L = 0.001512 mole molar mass of unknown acid= 0.2053g / 0.001512 mol =136 g/mol


It would flow toward the weaker solution. The intent of osmosis is to gain equilibrium, so the 15 percent solution would gain sugar content until, if you allowed the osmosis to go to completion, the two solutions had the same amount of sugar in them. "Going to completion" doesn't necessarily mean 20 percent concentration on both sides. If you were to make a gallon bag out of dialysis membrane, fill it with 15 percent solution and put a stirrer in it, then drop it into a 25,000-gallon reaction vessel full of 25 percent solution with a stirrer in it, you might wind up with 24.9999999999 percent sugar solution in both bags.


Firstly place 100 to 150 mg of aspirin into a 125 ml conical flask. Next proceed to mix in 15 ml of 95% ethanol solution and add 2 drops of phenolphthalein indicator. Then use the titration method to mix this solution against a standard solution of sodium hydroxide from a burette. Using the value obtained from the titration calculate the molarity of the aspirin. Then calculate the ratio of the observed molarity of aspirin with its theoretical molarity and finally multiply this ratio with 100 to obtain the percentage purity of the aspirin sample.

Molarity = moles of solute/liters of solution ( 15ml = 0.015 liters ) 2.9 M NaOH = moles NaOH/0.015 liters = 0.0435 moles of NaOH


CH3CH2CH2(CH2CH3)CH2OH 6 Carbons @ 12.01g/mol each = 72.06g/mol 15 Hydrogens @ 1.01g/mol each = 15.15g/mol 1 Oxygen @ 16.00g/mol = 16.00g/mol Add them up and that's your mass.


The pH scale is the negative of the logarithm of the hydrogen ion concentration (molarity) in a solution. Thus at pH 1 there are 1x 10-1 mol/liter of H+ present and at pH 14 there are 1x10-14 mole/liter present (much less) Obviously you could have 1x10-15 mol/liter present for a pH of 15 or even a fraction of of a mole to give a pH of less than 1 (pH 0.698 = 0,2 mole/liter.) At pH 0 the concentration would be 10 mol/liter Now what happens at lower than zero pH. Any acid that has a concentration of hydrogen ions with a molarity greater than 1 can be calculated to have a negative pH. The pH of 12M HCl would be -log(12) = -1.08. The proof of the concentration and pH would be physically difficult as the pH probes don't work well in this range (acid error).



It can takes up to 14 to 15 hours to freeze, depending on the amount of sugar you put in it. The higher the concentration of solute, the longer a solution takes to freeze. But unlike salt water, water containing sugar can freeze with the sugar trapped inside.


15 gm in a tablespoon sugar.


What is the solution set of 2x2 + x = 15



-15 + x100 is an expression, not an equation nor inequality. There is, therefore, no solution.-15 + x100 is an expression, not an equation nor inequality. There is, therefore, no solution.-15 + x100 is an expression, not an equation nor inequality. There is, therefore, no solution.-15 + x100 is an expression, not an equation nor inequality. There is, therefore, no solution.


It depends, is the solution 15% salt or 15% saturatedwith salt? If it is 15% salt, is is 85% water. If it is 15% saturated, it is 5.385%.


yes and no it is sugar, soda has sugar in it


That is approximately 8 pounds


15 ounces of sugar is 425.5 grams, 35.5 tbsp, or 106 tsp.
