23.82 kJ x (6.50g/0.432g) = ?
The above makes sense to me. Some, however, like to do these with ratio/proportion. That way is
(23.82 kJ/0.432g) = (x kJ/6.50g)
Solving for x we obtain
x kJ = 23.82 kJ x 6.50/0.432
When a 0.432g sample of a mixture of volatile hydrocarbons is burned in a bomb calorimeter with heat capacity of 3046 J/C, the temperature rises by 7.82C. How much energy (in KJ) is released during combustion.
**I got that answered**
3046x7.82C=23819.72J
the answer is negative and needs to converted to Kilo Joules.
So the answer is 23.82 KJ
I need help with the second part of the question which states.
How much energy (in kJ) would be released by the combustion of 6.50g of the same mixture??
