How do you calculate the length of the cube?
You would need to know other physical properties to be able to calculate the length. As you would need to know certain properties to be able to calculate the volume, for instance.
What tools would a student need to find a density of a metal cube?
You would need a balance to measure its mass. You would need a ruler to measure the length of its sides. Then you would need to calculate volume. Then divide the mass by the volume to get density.
How would you calculate the density if the object is cube?
The shape of an object is not enough to calculate its density. You also need its mass and then Density = Mass/Volume.
How to calculate mass with volume and molarity?
Not enough information. To calculate mass, you would need volume and density (mass = volume x density).
How many gallons in a 24x48'' container?
You would need a 3rd dimension to calculate a volume.
What would you need to do to calculate the molality of 10 mol of NaCl in 200 mols of water?
Convert the 200 mol of water to kilograms of water.
What would you need to do to calculate the molality of 10 mol NaCl in 200 mol of water?
Convert the 200 mol of water to kilograms of water.
What would you need to do to calculate the molality of 10 g of NaCl in 2kg of water?
58,49 g NaCl---------------------1 N10 g---------------------------------xx= 10/58,49=0,171 N58,49 is the molar mass of NaCl (for the foemula unit).Molality= 0,171/2=0,085

What would you need to do to calculate the molality of 10 mol of NaCl in 200 mol of water?
Convert the 200 mol of water to kilograms of water.
What would need to be done to calculate the molarity of 10 g of NaCl in 2 kg of water?
10 g of NaCl in 2 kg of water is 5 g of NaCl in 1 kg of water.The molar mass of NaCl is 39,666 g.5 g is equal to 0,318 molal.
What is the molality of a solution that has 4 mol of KCl in 0.800 kg of water A.?
4 mol over 0.800 kg
What is the molality of 16.1 g of Cl2 dissolved in a 5000 g water?
Molality(m)= moles of solute divided by kilograms of solvent you need to find the moles of solute of chloride first by using a conversion factor. 16.1g of Cl2 = 1mole divided by 70.90g of Cl = 0.23mol then you need to convert 5000g of water which is the solvent to kilograms which to convert it you move the decimal 3 units to the left so it is 5.000kg then you put it into the equation so it would be Molality(m)= 0.23mol divided by 5.000kg of solvent Molality= 0.05
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 would you need to do to calculate the molality of 0.2 kilogram of NaCl in 3 kilogram of water?
convert the .2 kg of NaCl to moles of NaCl.
Explain why molality is used for boiling point elevation and feezing point depression calculations and molarity is used for osmotic pressure calculations?
Molality is independent of temperature, so when you are trying to find changes in boiling and freezing points you need something that will stay constant regardless of the change in temperature. Molarity is temperature dependent and also is based on the volume of a solution, both of which are needed to calculate pressure using the ideal gas law, PV=nRT. Osmotic pressure is similar but we substitute the number of moles of the solution and the volume by using the molarity, you cannot do this with molality, since it is dependent on mass, not volume.
