Answer: Q= -34.6 J
Explanation: Use Q= mc∆T
c for solid lead is equal to 0.159 J/g°C
Substitute the values:
=14.8 g(0.159J/g°C)(23.7°C-38.4 °C)
= 14.8 g(0.159J/g°C) ( -14.7°C)
= -34.6 J
Cancel out the following units: g and °C so the remaining unit is in J.

N=m/M
so n = 25g/(1.01+19.00)g/mol
n = 25g/20.01g/mol
n = 1.2493
Round to 2 sig figs
So the answer is 1.2 mol
