How many grams are in 4.5 moles of sodium fluoride?
To find the number of grams in 4.5 moles of sodium fluoride, you would multiply the number of moles by the molar mass of sodium fluoride. The molar mass of sodium fluoride (NaF) is approximately 41 g/mol. So, 4.5 moles x 41 g/mol = 184.5 grams of sodium fluoride.
How many moles are there in 12.8 g of calcium fluoride?
To find the number of moles, you first need to determine the molar mass of calcium fluoride, which is 78.07 g/mol. Then, divide the given mass by the molar mass: 12.8 g / 78.07 g/mol = 0.164 moles. Therefore, there are 0.164 moles in 12.8 g of calcium fluoride.
How many moles of silver are contained in 7.00kg of silver?
To find the number of moles, we first need to calculate the molar mass of silver (Ag) which is 107.87 g/mol. Next, convert the mass of silver from kilograms to grams (7000g). Finally, divide the mass by the molar mass to find the number of moles, which results in 65.00 moles of silver.
What is the mass of 2.50 moles of silver?
To find the mass of 2.50 moles of silver, you can use its molar mass, which is approximately 107.87 g/mol. Multiply the number of moles by the molar mass: 2.50 moles × 107.87 g/mol = 269.675 grams. Therefore, the mass of 2.50 moles of silver is approximately 269.68 grams.
How many moles of silver are there in 129 g of silver?
To calculate the number of moles, we need to use the molar mass of silver, which is 107.87 g/mol. Divide the given mass by the molar mass to get the number of moles. Therefore, 129 g of silver is equal to approximately 1.2 moles of silver.
How many moles are in 58.2 grams of calcium fluoride?
To calculate the number of moles in calcium fluoride, you need to divide the given mass (58.2 g) by the molar mass of calcium fluoride (about 78.08 g/mol). Dividing 58.2 g by 78.08 g/mol gives you approximately 0.746 moles of calcium fluoride.
What mass of silver chloride can be produced from 1.59L of a 0.300M solution of silver nitrate?
To find the mass of silver chloride produced, first calculate the moles of silver nitrate using Molarity = moles/volume. Then, use the mole ratio from the balanced chemical equation to find the moles of silver chloride produced. Finally, multiply the moles of silver chloride by its molar mass to find the mass of silver chloride produced.
What is the mass of 2.6 moles of silver?
The molar mass of silver is approximately 107.87 g/mol. Therefore, the mass of 2.6 moles of silver would be 2.6 moles x 107.87 g/mol = 280.3 grams.
What is the molarity of 1.5 liters of an aqueous solution that contains 52 grams of lithium flouride?
The molarity of the solution can be calculated by first finding the moles of lithium fluoride using its molar mass, which is 25.94 g/mol for lithium and 19.00 g/mol for fluorine. Add these together to find the molar mass of lithium fluoride. Then, divide the mass of lithium fluoride by its molar mass to get the moles. Finally, divide the moles by the volume of the solution in liters to get the molarity.
What is the mass of twenty five moles of water?
1100 Grams
How many moles of fluoride ions are present in 10.4 g of NaF?
To calculate the number of moles of fluoride ions present in 10.4 g of NaF, you first need to determine the molar mass of NaF, which is 41 g/mol. Then, divide the given mass by the molar mass to find the number of moles of NaF (0.253 moles). Since there is one fluoride ion per molecule of NaF, there are also 0.253 moles of fluoride ions in 10.4 g of NaF.
How many atoms are present in 7.92g of calcium fluoride?
Calculate the number of moles of calcium fluoride by dividing the mass by its molar mass. The molar mass of calcium fluoride (CaF2) is 78.08 g/mol. Then, multiply the number of moles by Avogadro's number (6.022 x 10^23) to find the number of atoms present in 7.92g of calcium fluoride.
