Question

When 1.0 g of solid NaOH (Triangle Hsoln = –445.1 kJ/mol) dissolves in 10 L of water, how much heat is released?

would it be 445.1?

Answer 1

the 445kJ is per MOLE of NaOH, you're dissolving only 1 GRAM of NaOH...

Answer 2

so then would it be.....11.1kJ?

Answer 3

\[\frac{445kJ}{1mol NaOH}*\frac{1mol NaOH}{40g NaOH} = 11.1\frac{kJ}{g}\] yes

Answer 4

thank you!!
