What is the molarlity of a colution made by dissolving 6 moles of NaOH in 3 kg of water?
To find the molarity, we first need to convert the mass of water to moles. Since 1 kg of water is approximately 1000 moles, 3 kg of water is 3000 moles. Then, molarity is calculated by dividing the number of moles of solute (NaOH) by the volume of solution in liters. So, the molarity would be 6 moles / 3 L = 2 M.
How man moles are in 5.00 kg of Cu?
5.00 kg of Cu is equivalent to 78,68 moles.
How do you convert 2 moles of calcium to parts per million of calcium carbonate?
2 moles of calcium is 80,156 g; 1 part per million is 1 mg/kg (or L).
How many moles of gold are there in a piece of gold weighing 1.00kg?
To find the number of moles of gold in a 1.00 kg piece, we first convert the mass to grams: 1.00 kg = 1000 g. The molar mass of gold (Au) is approximately 197 g/mol. Using the formula for moles (moles = mass/molar mass), we calculate: 1000 g / 197 g/mol ≈ 5.08 moles of gold.
What is the molality of a solution containing 11.1 g Na2SO4 dissolved in 2269.2 g of water?
molality = moles solute/kg solventmoles solute = 11.1 g Na2SO4 x 1 mol/142 g = 0.0782 moleskg solvent = 2269.2 g x 1 kg/1000 g = 2.2692 kgmolality = 0.0782 moles/2.2692 kg = 0.0344 m (to 3 significant figures)
What mass in kg does 5.84 moles of titanium have?
The molar mass of titanium is approximately 47.87 g/mol. To convert moles to kilograms, you need to multiply the number of moles by the molar mass and then convert from grams to kilograms. Therefore, 5.84 moles of titanium would have a mass of approximately 279.49 kg.

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.
What is the molarlity of a colution made by dissolving 6 moles of NaOH in 3 kg of water?
To find the molarity, we first need to convert the mass of water to moles. Since 1 kg of water is approximately 1000 moles, 3 kg of water is 3000 moles. Then, molarity is calculated by dividing the number of moles of solute (NaOH) by the volume of solution in liters. So, the molarity would be 6 moles / 3 L = 2 M.

0.33 mol/kg
How many moles are there in fifteen kg of butane?
To find the number of moles in fifteen kg of butane, first calculate the molar mass of butane (C4H10) which is 58.12 g/mol. Then convert fifteen kg to grams (15000 g). Finally, divide the mass in grams by the molar mass to find the number of moles, which in this case is approximately 258.27 moles.
How many moles are in 1 kg of C2H6O2?
To find the number of moles in 1 kg of C2H6O2, we first need to calculate the molar mass of C2H6O2: (212.01) + (61.01) + (2*16.00) = 62.07 g/mol. Then, we convert 1 kg to grams: 1 kg = 1000 g. Finally, we divide the mass by the molar mass to find the number of moles: 1000 g / 62.07 g/mol = 16.12 moles.
How much is 142 pounds in kilograms?
142 kilograms weigh 51.1 pounds on the moon, 112.4 pounds on Mars, and 313.1 pounds on earth. (rounded)
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 kg of NaCI in 3 kg of?
To calculate the molality of 0.2 kg of NaCl in 3 kg of water, first determine the number of moles of NaCl by using its molar mass (approximately 58.44 g/mol). Convert 0.2 kg of NaCl to grams (200 g) and calculate the moles: ( \text{moles} = \frac{200 \text{ g}}{58.44 \text{ g/mol}} ). Finally, use the formula for molality, which is moles of solute per kilogram of solvent: ( \text{molality} = \frac{\text{moles of NaCl}}{3 \text{ kg of water}} ).
What number of moles of O2 is needed to produce 142 grams of P4O10 from P?
We first calculate the molar mass of P4O10, which is 284 g/mol. Then we convert the given mass of P4O10 (142 g) to moles using its molar mass. There is a 1:4 molar ratio between P4O10 and O2 in the reaction, so we multiply the moles of P4O10 by 4 to find the moles of O2 needed.
