Answer : The specific heat of the metal is, [tex]1.11J/g^oC[/tex]
Explanation
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
[tex]q_1=-q_2[/tex]
[tex]m_1\times c_1\times (T_f-T_1)=-m_2\times c_2\times (T_f-T_2)[/tex]
where,
[tex]c_1[/tex] = specific heat of metal = ?
[tex]c_2[/tex] = specific heat of water = [tex]4.18J/g^oC[/tex]
[tex]m_1[/tex] = mass of metal = 95.0g
[tex]m_2[/tex] = mass of water = 50.0 g
[tex]T_f[/tex] = final temperature of mixture = [tex]48.5^oC[/tex]
[tex]T_1[/tex] = initial temperature of metal = [tex]100.0.0^oC[/tex]
[tex]T_2[/tex] = initial temperature of water = [tex]22.5^oC[/tex]
Now put all the given values in the above formula, we get
[tex](95.0g)\times c_1\times (48.5-100.0)^oC=-[(50.0g)\times 4.18J/g^oC\times (48.5-22.5)^oC][/tex]
[tex]c_1=1.11J/g^oC[/tex]
Therefore, the specific heat of the metal is, [tex]1.11J/g^oC[/tex]
