2.70 m = 2.70 moles/kg solvent3250 g solvent = 3.25 kg solvent
2.70 moles/kg x 3.25 kg = 8.775 moles NaNO3 = 8.78 moles NaNO3 (3 significant figures)

What is the volume of 3.0 M solution of NaCl made with 526g of solute?
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 ---------------------------------
What is the molality of a solution made by dissolving 2 moles of NaOH in 10 kg?
The molality is 0,2.
What is the molarity of a solution made by dissolving 4 moles of solute in 4 liters of solution?
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.
What is the molarity of a sugar solution made from 21.0 moles of sugar with the volume of 52.0L?
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.
What is the molality of a solution made by dissolving 2 moles of NaOH in 6kg of water?
0.33 mol/kg
What is molarity of a solution made by dissolving 2 moles of NaOH in 6 kg of water?
The molarity is 0,33.
What is the molarity of a solution made by dissolving 2 moles of NaOH in 10 kg of water?
The molarity is 0,2.
What is the molarity of a solution that is made using 1.2 moles of a substance in 500mL?
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 that is made by dissolving 75.0 grams of MgCl2 in 500.0 milliliters of solution?
Need moles MgCl2 75.0 grams MgCl2 (1 mole MgCl2/95.21 grams) = 0.7877 mole MgCl2 ================now, Molarity = moles of solute/Liters of solution ( 500.0 milliliters = 0.5 Liters ) Molarity = 0.7877 moles MgCl2/0.5 Liters = 1.58 M MgCl2 solution --------------------------------
What is the molarity of a 2.000 L solution thatis made from 14.60 g of NaCL?
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--------------------------------
What is the molality of a solution made by dissolving two moles of NaOH in 6 kg of water?
Molality is expressed as moles solute/kg solvent. Moles of solute = 2. Kg solvent = 6.Molality = 2 moles/6 kg = 0.33 molal
What is the molality of a solution made by dissolving 2 moles of NaOH in 6 kg?
Molality (m) is defined as moles of solute per kg of solvent.Thus, 2 moles/6 kg = 0.33 molal or 0.3 m.
