## How big is a mole of uranium?

One mole of U238 ( 6.022 X 10^23 atoms) is **238 grams**; one mole of U235 is 235 grams. The difference in molecular weight between a mole of U235 and U238 is 3 grams, the secret to enriching uranium.

## How many convert grams to moles?

To correctly estimate the number of moles, n , of a substance of a specific mass, m , (in grams), you need to follow the grams to moles formula: **n = m / M** , where, M is the molar mass of this material.

## How many L are in a mol?

If we know the volume of a gas sample at STP, we can determine how much mass is present. Assume we have **867 liters** of N_{2} at STP. What is the mass of the nitrogen gas? Molar volume at STP can be used to convert from moles to gas volume and from gas volume to moles.

## How many grams does 1 mole of gold weigh?

Furthermore, the atomic mass of gold is 196.9665. That means that one mole of gold weighs **196.9665 grams** (196.9665 g/mol). Based on that information, to convert 1 moles of gold to grams, we multiply 1 moles of gold by 196.9665.

## How many moles are in 238.03 grams of uranium?

Alternatively, we could work out the molar quantity, knowing that Avogadro’s number , NA uranium atoms have a mass of 238.03⋅g . We thus speak of the molar mass of uranium as 238.03⋅g⋅mol−1 . And thus moles of uranium=**1000⋅g238.03**⋅g⋅mol−1=4.20⋅mol .

## How many protons does 1 gram of uranium have?

Uranium has an atomic number of 92 which means there are **92 protons** and 92 electrons in the atomic structure. U-238 has 146 neutrons in the nucleus, but the number of neutrons can vary from 141 to 146. Because uranium is radioactive, it is constantly emitting particles and changing into other elements.

## How many atoms does 1 mole of uranium have?

You also know that 1 mole of uranium-235 will contain **6.022⋅1023 atoms** of uranium-235, as given by Avogadro’s constant.

## How many atoms are in 1kg of uranium 235?

so the answer is **2.56*10^24 atoms**.
