What would you need to do to calculate molality of 10g of NaCI in 2Kg of water?
To calculate the molality of a solution, you need to divide the moles of the solute (in this case, NaCl) by the mass of the solvent (water) in kilograms. First, convert the mass of NaCl to moles using its molar mass. Then, calculate the molality by dividing the moles of NaCl by the mass of water in kilograms.
What would you need to do to calculate the molality of 10g of NaCI in 2kg of water?
To calculate the molality of 10 g of NaCl in 2 kg of water, first, determine the number of moles of NaCl by using its molar mass (approximately 58.44 g/mol). Divide the mass of NaCl (10 g) by its molar mass to find the moles. Then, use the formula for molality (m) which is moles of solute per kilogram of solvent: m = moles of NaCl / mass of water in kg (2 kg). Finally, substitute the values to get the molality.
What is the molality of a solution composed of 20.2 g NaCl dissolved in 685 g of water?
The answer is 0,505.
What would you need to do to calculate the molality of 10 g of NaCI in 2kg of water?
To calculate the molality of NaCl in water, first, you need to determine the number of moles of NaCl by using its molar mass (approximately 58.44 g/mol). For 10 g of NaCl, divide 10 g by 58.44 g/mol to find the moles. Then, use the mass of the solvent (water) in kilograms; since you have 2 kg of water, molality is calculated as the number of moles of solute divided by the mass of solvent in kilograms. The formula is: molality (m) = moles of solute / kg of solvent.
How do you calculate the molality of 10g of NaCI in 2kg of water?
To calculate the molality (m) of a solution, use the formula: [ \text{molality} (m) = \frac{\text{moles of solute}}{\text{mass of solvent (kg)}}. ] First, convert the mass of NaCl into moles by using its molar mass (approximately 58.44 g/mol). For 10 g of NaCl, you have: [ \text{moles of NaCl} = \frac{10 , \text{g}}{58.44 , \text{g/mol}} \approx 0.171 , \text{mol}. ] Then, divide the moles by the mass of the solvent (water) in kilograms: [ m = \frac{0.171 , \text{mol}}{2 , \text{kg}} \approx 0.0855 , \text{mol/kg}. ] So, the molality of the solution is approximately 0.0855 mol/kg.
What is the molality of a solution that has 70g of NaCl dissolved in 300g of water?
Molality(m)= moles of solute divided by kilograms(kg) of solvent you need to find the moles of NaCl by using a conversion factor 70g NaCl = 1mol divided by 58.44g NaCl =1.20mol then you need to convert 300g of water which is the solvent to kilograms by moving the decimal over 3 units to the left which makes .300 kg of solvent Molality= 1.20mol divided by .300kg Molality=4.00
What is the molality of .630g of NaCl dissolved in 525g of water?
To find molality, first convert grams of NaCl to moles: 0.630g NaCl / 58.44 g/mol NaCl = 0.0108 mol NaCl. Next, calculate molality using moles of solute and mass of solvent: molality = moles of solute / kg of solvent = 0.0108 mol NaCl / 0.525 kg water = 0.0206 mol/kg.
