What element has 235 mass number?
Uranium-235 is the element with a mass number of 235. It is a radioactive isotope of uranium that is used in nuclear reactors and nuclear weapons.
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
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.
Why must uranium be enriched?
Uranium must be enriched to increase the concentration of the fissile isotope uranium-235 (U-235) for use in nuclear reactors and weapons. Natural uranium contains only about 0.7% U-235, which is insufficient for sustaining a nuclear chain reaction. Enrichment raises the U-235 content to levels suitable for efficient energy production or for critical mass in weapons. This process is essential to ensure that reactors operate effectively and safely, as well as to meet specific requirements for nuclear materials.
What is the mass in grams of 1.92 moles of uranium atoms What if your answer?
To find the mass of 1.92 moles of uranium atoms, you can use the molar mass of uranium, which is approximately 238 grams per mole. Multiply the number of moles by the molar mass: 1.92 moles × 238 g/mole = 456.96 grams. Therefore, the mass of 1.92 moles of uranium atoms is about 457 grams.

What are the three main advantages of a fusion reactor compared to a fission reactor?
Fusion reactors produce less radioactive waste compared to fission reactors. Fusion reactors use abundant sources such as deuterium and lithium for fuel, while fission reactors use limited sources like uranium. Fusion reactions release more energy per unit mass of fuel compared to fission reactions.

A difference between uranium 235 and plutonium 239?
Uranium 235 has 92 protons and electrons, 143 neutrons, atomic mass is cca. 235, is a natural isotope. Plutonium 239 has 94 protons and electrons, 145 neutrons, atomic mass is cca. 239, is an artificial isotope. Plutonium is more toxic than uranium. Also are differences in the types of radiations emmited, half-life and many other chemical and physical properties.
What is the mass in grams of 1.92 moles of uranium atoms What if your answer?
To find the mass of 1.92 moles of uranium atoms, you can use the molar mass of uranium, which is approximately 238 grams per mole. Multiply the number of moles by the molar mass: 1.92 moles × 238 g/mole = 456.96 grams. Therefore, the mass of 1.92 moles of uranium atoms is about 457 grams.
Gram of molar mass in uranium?
1 atom gram of natural uranium = 238,028 91 grams
Does a critical mass of uranium require enriched uranium?
Yes, a critical mass of uranium typically requires enriched uranium. Enriched uranium has a higher concentration of the fissile isotope uranium-235, which is necessary for sustaining a nuclear chain reaction in a reactor or weapon. Unenriched uranium, which is mostly uranium-238, requires a larger critical mass to achieve a sustained chain reaction.
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.
Which of the following are differences between nuclear reactors and nuclear bombs?
Purpose: Nuclear reactors are designed to produce electricity through controlled nuclear fission, while nuclear bombs are designed to release a large amount of energy in an uncontrolled nuclear fission chain reaction. Control: Nuclear reactors have various safety features and control mechanisms to regulate the nuclear fission process, while nuclear bombs have no such controls and are designed for maximum energy release. Fuel Enrichment: Nuclear reactors typically use low-enriched uranium or plutonium as fuel, while nuclear bombs require highly enriched uranium or plutonium to achieve a rapid, explosive chain reaction.
Does a critical mass require enriched uranium?
No, a critical mass does not require enriched uranium. A critical mass is the minimum amount of fissile material needed to sustain a nuclear chain reaction. While enriched uranium is a commonly used fissile material for nuclear reactions, other materials such as plutonium can also achieve criticality.
