3 Litre ( = 6.00 mol / 2.00 mol/L )
1.5L
Molarity is moles in every litre. Therefore you have to convert this to find out the moles in each litre. 21/52 is 0.404 molar.
Molarity (M) is defined as moles of solute/liters of solution. Assuming the final volume is 500 ml (0.5 liters), then M = 1.2 moles/0.5 liters = 2.4 M
Find moles NaCl first.14.60 grams NaCl (1 mole NaCl/58.44 grams)= 0.2498 moles NaCl================Now,Molarity = moles of solute/Liters of solutionMolarity = 0.2498 moles NaCl/2.000 Liters= 0.1249 M NaCl solution--------------------------------
Molality (m) is defined as moles of solute per kg of solvent.Thus, 2 moles/6 kg = 0.33 molal or 0.3 m.
this is because the amount of solute in the solution will have the same number of moles as that of the solid.
Need to find moles NaCl. 526 grams NaCl (1 mole NaCl/58.44 grams) = 9.0 moles NaCl --------------------------------now, Molarity = moles of solute/Liters of solution or, for our purposes Liters of solution = moles of solute/Molarity Liters of solution = 9.0 moles NaCl/3.0 M = 3.0 liters in volume ---------------------------------
Molarity is moles in every litre. Therefore you have to convert this to find out the moles in each litre. 21/52 is 0.404 molar.
Molarity (M) is defined as moles of solute/liters of solution. Assuming the final volume is 500 ml (0.5 liters), then M = 1.2 moles/0.5 liters = 2.4 M
what is the molarity of a solution prepared by dissolving 36.0g of NaOH in enough water to make 1.50 liter of solution?
concentration or molarity = number of moles/volume number of moles (n) = mass in grams of nacl/relative atomic mass of nacl n=17.52/(23+35.5) n = 0.2994872 mol volume = 2000/1000 = 2dm^3 molarity = 0.2994872/2 =0.15mol/dm^3
It depends highly on the compound to be dissolved and the solvent. Molarity is measured my moles per litre, and if you don't know the molar mass of the compound, you can't work out the molarity.
Al2(SO3)3 has r.f.m.= (2x27 + 3x32 + 9x16) = 294 Thus 25 g is 25/294 = 0.085 moles of aluminium sulfite. We have 0.085 moles in 175 ml of solution, which would be 0.085 x 1000/175 moles in a litre = 0.486 M
The molality is 0,2.
Molarity means moles per litre. Therefore, you have to get it as a term in a litre. 4 litres /4 is a litre, therefore 4 moles/4 is 1 mole. So it is 1 molar.
0.33 mol/kg
The molarity is 0,33.
The molarity is 0,2.
