Answer:
I never did this but i think its d 37.5٪ lmk if i got it right pls and srry if i didnt
The final temperature, t₂ = 30.9 °C
<h3>Further explanation</h3>
Given
24.0 kJ of heat = 24,000 J
Mass of calorimeter = 1.3 kg = 1300 g
Cs = 3.41 J/g°C
t₁= 25.5 °C
Required
The final temperature, t₂
Solution
Q = m.Cs.Δt
Q out (combustion of compound) = Q in (calorimeter)
24,000 = 1300 x 3.41 x (t₂-25.5)
t₂ = 30.9 °C
Answer:
We have the final answer as
<h2>0.68 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 40.8 g
volume = 60 mL
The density is

We have the final answer as
<h3>0.68 g/mL</h3>
Hope this helps you
