Calculate mass of uranium from 175.5 of uranium hexafluoride?
To calculate the mass of uranium, we need to know the molar mass of uranium hexafluoride (UF6), which is approximately 352 g/mol. Given that the sample has 175.5 g of UF6, we can calculate the mass of uranium by multiplying the molar mass of uranium by the ratio of the molar mass of uranium to the molar mass of UF6 (238.03 g/mol / 352 g/mol) and then multiplying by the mass of UF6 provided. This would result in approximately 119.196 g of uranium in 175.5 g of UF6.
How many moles are in 119 grams of uranium?
To find the number of moles in 119 grams of uranium, you need to divide the given mass by the molar mass of uranium. The molar mass of uranium is approximately 238.03 grams/mol. Dividing 119 grams by 238.03 grams/mol gives you 0.5 moles of uranium.
What is the molar mass of one mole of Uranium?
1 atomgram of uranium = 238,02891 gramsAnswer:The molar mass of Uranium is 238.03 g/mol
How do you find the number moles of uranium are there in 3 cubic centimeters of uranium and how many are there?
To find the number of moles of uranium in 3 cubic centimeters, you would need to know the density of uranium. Once you know the density, you can calculate the mass of 3 cubic centimeters of uranium and then use the molar mass of uranium to convert the mass to moles. The number of moles can be calculated using the formula: moles = mass (g) / molar mass (g/mol).
What is the mass of 7.50 moles of uranium?
The mass of 7,5 mole of natural uranium is 238,02891 x 7,5 g.
To two decimal places write the molar masses of carbon neon iron and uranium?
Atomic mass: Carbon - 12,01 Neon - 20,18 Iron - 55,84 Uranium - 238,03
How many uranium atoms are in 6g of pure uranium?
To find the number of uranium atoms in 6g of pure uranium, we first need to calculate the molar mass of uranium, which is approximately 238.03 g/mol. Then, we use Avogadro's number (6.022 x 10^23 atoms/mol) to convert the mass to number of atoms. So, 6g of uranium contains about 6.022 × 10^23 atoms.
How many moles are in 6.22 micro grams of uranium when the table shows uranium at an atomic mass of 238.0?
To find the number of moles in 6.22 micrograms of Uranium, you first need to calculate the number of moles using the formula: Moles = Mass / Molar mass. The molar mass of Uranium is 238.0 g/mol. Convert 6.22 micrograms to grams by dividing by 1,000,000. Then, divide the mass in grams by the molar mass to find the number of moles.
How many uranium atoms are the there in 6g?
To find the number of uranium atoms in 6g, you need to know the atomic mass of uranium. Uranium has an atomic mass of about 238 g/mol. Using this information, you can calculate that there are approximately 1.34 x 10^22 uranium atoms in 6g.
What is the empirical formula of a fluoride of uranium containing 24.2 percent fluorine and the rest uranium?
The empirical formula of the fluoride of uranium can be determined by converting the percentages to moles. Since uranium has an atomic mass of about 238 g/mol and fluorine 19 g/mol, the ratio of moles of fluorine to uranium is approximately 4:1. Therefore, the empirical formula is UF4.
Calculate the mass, in grams, of each of the following samples.1.7 mol aluminum 1.400e-15 Tmol carbon dioxide 7.7e12 pmol of sodium nitrate 2.73e-4 kmol of C2H6O 1.02 ✕ 10-9 Mmol of uranium 4.01 mmol hydrobromic acid?
Mass (g) = Number of moles (mol) x Molar mass (g/mol) Here are the calculations for each sample: 7 moles of aluminum (Al): The molar mass of Al is approximately 26.98 g/mol. Mass = 7 mol x 26.98 g/mol = 188.86 g 1.400e-15 teramoles (Tmol) of carbon dioxide (CO2): The molar mass of CO2 is approximately 44.01 g/mol. Mass = 1.400e-15 mol x 44.01 g/mol = 6.16e-14 g 7.7e12 picomoles (pmol) of sodium nitrate (NaNO3): The molar mass of NaNO3 is approximately 85 g/mol. Mass = 7.7e12 mol x 85 g/mol = 6.59e-10 g 2.73e-4 kilomoles (kmol) of C2H6O: The molar mass of C2H6O (ethanol) is approximately 46.07 g/mol. Mass = 2.73e-4 mol x 46.07 g/mol = 0.1256 g 1.02e-9 megamoles (Mmol) of uranium (U): The molar mass of uranium is approximately 238.03 g/mol. Mass = 1.02e-9 mol x 238.03 g/mol = 2.43e-7 g 4.01 millimoles (mmol) of hydrobromic acid (HBr): The molar mass of HBr is approximately 80.91 g/mol. Mass = 4.01e-3 mol x 80.91 g/mol = 0.3247 g So, the mass of each sample is as follows: 188.86 grams of aluminum 6.16e-14 grams of carbon dioxide 6.59e-10 grams of sodium nitrate 0.1256 grams of C2H6O 2.43e-7 grams of uranium 0.3247 grams of hydrobromic acid.
7.5 times 10 to the 21 uranium atoms equals how many grams?
To convert uranium atoms to grams, you need to know the molar mass of uranium. Uranium's molar mass is approximately 238.03 g/mol. Therefore, 7.5 x 10^21 uranium atoms would weigh approximately 0.625 grams.
