Answer:
<h2>0.52 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
volume = final volume of water - initial volume of water
volume = 35 - 8 = 27 mL
We have

We have the final answer as
<h3>0.52 g/mL</h3>
Hope this helps you
Energy= 2381 joules
heat= Mass(kg) *change in temperature(K) * Cp
2381=0.155*(15)*Cp
Cp=1024 J/kg K
