Answer:
The answer is
<h2>5.0 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 35 g
volume = 7 cm³
The density is
We have the final answer as
<h3>5.0 g/cm³</h3>

2-butane is the correct answer
Let's apply the concept of conservation of energy.
∑E = 0
Energy released by ice + Energy absorbed by water = 0
Energy released by ice = - Energy absorbed by water
(mass of alloy)(Cp,ice(Tf - T₀) = -(mass of water)(Cp,water)(Tf - T₀)
where Cp is the specific heat capacity
*Cp for ice is 2.108 J/g·°C
*Cp for water is 4.184 J/g·°C
Substituting the values,
(2×20 g)(2.108 J/g·°C)(Tf - -13) = -(255 g)(4.184 J/g·°C)(Tf - 25)
Solving for Tf,
<em>Tf = 22.22 °C</em>
