Convert 62.13 kg Al to grams.
62.13 kg (1000 g/kg) = 62130 g Al
Convert grams to moles using the atomic weight of Al from the Periodic Table.
Al is 26.9815 g/mol
62130 g / (26.9815 g/mol) = 2302.6 mol Al
In significant figures, that is 2303 mol Al.
In scientific notation, that is 2.303 x 104 mol Al.

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 is the molality of a solution made by dissolving 2 moles of NaOH in 6kg of water?

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 kilograms of HF are needed to completely react with 7.75 kg or UO2?
To calculate the amount of HF needed to react with 7.75 kg of UO2, you first need to determine the molar ratio between UO2 and HF from the balanced chemical equation. Then convert 7.75 kg of UO2 to moles using the molar mass of UO2 and apply the molar ratio to find the moles of HF required. Finally, convert the moles of HF to kilograms using the molar mass of HF.

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.

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.
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
