What are the steps needed when solving problem like this?
a compound of uranium and fluorine is used to generate uranium for nuclear power plants. the gas can be decomposed to yield 2.09 parts by mass of uranium for every 1 part by mass of fluorine. if the relative mass of a uranium atom is 238 and the relative mass of a fluorine atom is 19, calculate the number of fluorine atoms that are combined with one uranium atom.

The number of fluorine atoms that combine with one uranium atom are 6.

Explanation:

We are given an unknown gas of uranium and fluorine atom and when it is decomposed, it produces 2.09 parts of uranium atoms for every 1 part of fluorine atom.

Relative mass of Uranium = 238 g

Relative mass of Fluorine = 19 g

Number of atoms of uranium present in a given relative mass =

Number of atoms of fluorine present in given relative mass =

For 0.0087 atoms of uranium are produced when 0.05 atoms of fluorine are produced.

So, 1 atom of uranium are produced when = atoms of Fluorine atoms.

Hence, 6 atoms of fluorine atoms are produced when 1 uranium atom is produced.

sry but any answer choices

i believe the answer is a.
