I think that if you were to look up the definition of "heat capacity" that would make what you need to do clear.

I am still having issues placing these numbers in the correct spot. Is there anyone that can point me in the right direction, or share some links that would help me with this further.

$Q = m \cdot C \cdot \Delta T$

you are given $Q$ , $m$ , and $\Delta T$ ... solve for $C$

6. ## Re: Chemisty confusions

47.5J(13.2g)(4.18j)(1.72c)= 341.506 grams
signif digits 341.5

Is this right?

7. ## Re: Chemisty confusions

Q=m·c·Δt
47.5 joules = 13.2g·4.18Joules·1.72°c
47.5 = 94.90272g

Do I divide this I'm not sure if this is right?Can someone point me in the right direction?

$Q = m \cdot C \cdot \Delta T$

$\frac{Q}{m \cdot \Delta T} = C$

substitute in your given values and calculate the specific heat, C.
