Calculating Heat Needed to Raise Water Temperature from 8.2◦C to 73◦C

[DrMcDreamy]

Homework Statement

This is for my physics homework and I haven't done gen chem in a while so I was wondering if this was right:

You need to raise the temperature of 62 g of water from 8.2◦C to 73◦C. How much heat is needed to accomplish this? The specific heat of water is 4180 J/kg ·◦C. Answer in units of J.

Homework Equations

Q=mc\DeltaT

The Attempt at a Solution

Q=(0.062 kg)(4180 J/kg◦C)(73◦C-8.2◦C) = 16,793.568 J

Is that right? TIA

Correct approach, again problem with SD. Answering 17 kJ, or 16.8 kJ will do.

Thank you! I put in 16,794 and it was right.
