Tin reacts with fluorine to form two different compounds, a and b. compound a contains 38.5 g of tin for each 12.3 g of fluorine. compound b contains 56.5 g of tin for each 36.2 g of fluorine. what is the lowest whole-number mass ratio of tin that combines with a given mass of fluorine?

Tin to Fluorine mass ratios:
1) For compound A:
38.5/12.3
= 3.13
2) For compound B:
56.5/36.2
= 1.56
The lowest whole number mass ratio is 2. It cannot be 1 because it is less than that required for compound B.

In compound A, the mass ratio of Tin to Fluorine is 1 : 2

In compound B, the mass ratio of Tin to Fluorine is 1 : 4

Explanation: For the reaction of Tin and Fluorine, the reaction follows:

To calculate the mass ratio, we simply find the mole ratio and for that we need to find the moles of Tin and fluorine respectively for each compound and then divide it by the lowest number of moles.

Molar mass Tin = 118.71g/mol

Molar mass Fluorine = 19g/mol

Formula to calculate the moles is:

For Compound A:

Given mass of Tin = 38.5 g

Moles of Tin =

Given mass of Fluorine = 12.3 g

Moles of Fluorine =

Mole ratio of Tin is =

Mole ratio of Fluorine =

Mass ratio of Tin and fluorine is 1 : 2. The compound formed is

For Compound B:

Given mass of Tin = 56.5 g

Moles of Tin =

Given mass of Fluorine = 36.2 g

Moles of Fluorine =

Mole ratio of Tin is =

Mole ratio of Fluorine =

Mass ratio of Tin and fluorine is 1 : 24 The compound formed is
