Question

Find the formula mass of the compound, then divide the individual element total by the total mass-move the decimal over two to change it to percentage SiF4

Answer 1

Step-by-step explanation:

Here, we start by calculating the formula mass of the compound

We can get this by using the atomic masses of the elements

The atomic mass of silicon is 28 amu

The atomic mass of fluorine is 19 amu

The formula mass of the given compound is thus:

`28\text{ + 4\lparen19\rparen = 104 g/mol}`

Now, we divide the individual total mass by element by the formula mass

For Silicon, we have:

`(28)/(104)\text{ = 0.27}`

For Fluorine, we have:

`(76)/(104)\text{ = 0.73}`
