[q labels=”bottom”]Set up the calculation to find out how many moles of SiCl_{4} are in 56.5g of SiCl_{4}.

[l]56.5g SiCl_{4}

**[fx] The value given in the problem is your starting numbers.**

**[f*] Great!**

[l]1 mol SiCl_{4}

**[fx] What you are trying to find goes on the top of the ratio.**

**[f*] Good!**

[l]169.89g SiCl_{4}

**[fx] The molar mass goes on the bottom of the ratio.**

**[f*] Correct!**

[q labels=”bottom”]Set up the calculation to find out how many grams of SnI_{2} are in 0.56moles of SnI_{2}.

[l]0.56mol SnI_{2}

**[fx] The value given in the problem is your starting numbers.**

**[f*] Good!**
