How can one determine the molality of a solution?
To determine the molality of a solution, you need to divide the moles of solute by the mass of the solvent in kilograms. Molality is calculated as moles of solute divided by kilograms of solvent.
How many kilograms are in 25 moles?
To convert from moles to kilograms, you need to use the molar mass of the substance. The molar mass of the substance in question would determine how many kilograms are in 25 moles. You can calculate it by multiplying the number of moles by the molar mass.
How many atoms are contained in 97.6g of platinum?
To determine the number of atoms in 97.6g of platinum, you first need to calculate the number of moles of platinum using its molar mass (195.08 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles of platinum to atoms. This calculation will give you the total number of atoms in 97.6g of platinum.
How can one determine the molal concentration of a solution?
To determine the molal concentration of a solution, you need to divide the moles of solute by the mass of the solvent in kilograms. This calculation gives you the molality of the solution, which is expressed in moles of solute per kilogram of solvent.
How many moles of platinum Pt are there in 10 g of platinum?
To find the number of moles of platinum in 10g, divide the mass by the molar mass of platinum. The molar mass of platinum is approximately 195.08 g/mol. Therefore, there are 0.051 moles of platinum in 10g.
How many moles of platinum would be in 10.0 g of this metal?
10 g platinum is equal to 0,05 moles.
What is the mass in grams of 0.48 molar of platinum?
To find the mass of 0.48 moles of platinum, you would multiply the number of moles by the molar mass of platinum. The molar mass of platinum is approximately 195.08 g/mol, so the mass of 0.48 moles of platinum would be 0.48 moles * 195.08 g/mol ≈ 93.62 grams.
How many moles are in 0.0034 g platinum?
To find the number of moles, you need to divide the mass of the substance by its molar mass. The molar mass of platinum is 195.08 g/mol (rounded to two decimal places). Therefore, for 0.0034 g of platinum: 0.0034 g / 195.08 g/mol ≈ 0.000017 moles of platinum.
How many moles are in 14.5 cm3 of platinum. The density of platinum 21.45 gcm3?
The answer is 1,594 mol.
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.
How many kilograms of silver are in 4.35 moles of silver?
4,35 moles of silver is equal to 469 g (0,469 kg).
How can one determine the number of moles in a substance using the formula for finding moles?
To determine the number of moles in a substance, you can use the formula: moles mass / molar mass. Simply divide the mass of the substance by its molar mass to find the number of moles.
