What is the molality of a solution that contains 2 moles of glycerin and dissolved in 1000 g of water?
The molality of a solution is calculated by dividing the moles of solute by the mass of the solvent in kilograms. In this case, there are 2 moles of glycerin dissolved in 1000 g of water, which is equivalent to 1 kg. Therefore, the molality is 2 mol / 1 kg = 2 mol/kg.
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 many the mole of CO 2 contains?
atomic weight of carbon dioxide is 2 * 16 + 12 = 44 1 kg = 1000 g 1 kg of co2 has 1000/44 = 22.7 moles yeh i think that's wrong lol isn't it 3.37E25?
How many moles of KF are contained in 347 g of water in a 0.175 m KF solution?
The definition of 0.175 m KF is that 1 kg of water contains 0.175 moles of KF. Thus, 347 g of water is equivalent to 0.347 kg, and to find moles of KF, you calculate as follows:0.175 moles/Kg x 0.347 kg = 0.0607 moles of KF are present (3 significant figures).
How many kg in one kg?
Depends on the molecule. Look in the periodic table at the atomic weights. This number is the grams per mole. Carbon for example has 12 grams in each mole.
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 many moles of sodium are in 5.13 kg of sodium?
Quite a few! 5.13 kilograms sodium (1000 grams/1 kg)(1 mole Na/22.99 grams) = 223 moles of sodium =================
Calculate with clear arrangements how many moles of oxygen are needed to burn 1 kg of ethane and 1 kg of ethanol, respectively?
nothing
What is the molality of a solution made by dissolving 2 moles of NaOH in 6 kg of water?
0.33 mol/kg (apex)

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.
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 a solution composed of 38.0 g of cane sugar (C12H 22O11) dissolved in 175 g of water?
First, calculate the moles of cane sugar: 38.0 g / 342.3 g/mol = 0.111 moles. Then, calculate the molality using the formula: molality = moles of solute / kg of solvent. Since 175 g of water is equivalent to 0.175 kg, molality = 0.111 moles / 0.175 kg = 0.634 mol/kg.

How many bou in 1 kg OF NEOMYCIN SULPHATE?
The molecular weight of neomycin sulfate is approximately 615.6 g/mol. To calculate the number of moles in 1 kg of neomycin sulfate, you would divide 1000 g by the molecular weight. This gives you approximately 1.62 moles of neomycin sulfate in 1 kg. Since 1 mole of a compound contains Avogadro's number of molecules (6.022 x 10^23), there are approximately 9.75 x 10^23 molecules of neomycin sulfate in 1 kg.
