Minimum volume of benzene with percentage yield It's not very clear to me why though... if volume : yield = 100% : 6.573 cm^3, then I should find for 35.2% : Volume. However, it still doesn't divide by 35.2. Also everything is in a 1:1 ratio why do I need 100 times more benene? |

Calculation of Kc Yes, I used that formula, I took the total HI concentration as 1.5 because it is the amount we get directly from the graph and didn't square it. |

Ratio between the corresponding force constants of Cl2 and F2 How did you get the reduced mass as m/2. |

Calculating percentage of Zn in a coin This is from a College Preliminary test. Apparently requires Advanced Level Chemistry knowledge only. |

Find the w/w percentage nitrogen in an ammonium nitrate solution I took the density as the density of ammonium nitrate. Mr is molar mass. |
