Answer:

The mass of silver is 49 g (0.049 kg).

Explanation:

Initial temperature = [tex]30^{o}[/tex]C

Final temperature = [tex]40^{o}[/tex]C

Quantity of heat required = 117.5 J

Specific heat capacity of silver = 0.240 J/g[tex]^{o} C[/tex]

mass of the silver can be determined by;

Q = mcΔθ

Where: Q is the quantity of heat required, m is the mass of substance, c is the specific heat capacity of the substance and Δθ is the change in temperature.

So that,

117.5 = m x 0.240 x (40 - 30)

117.5  = m x 0.24 x 10

        = 2.4m

m = [tex]\frac{117.5}{2.4}[/tex]

   = 48.9583

m ≅

m = 49 g

The mass of silver is 49 g (0.049 kg).
