Answer:

19.3 g/cm³

Explanation:

From the question given above, the following data were obtained:

Mass of nugget of gold = 965 g

Volume of nugget of gold = 50 cm³

Density =?

The density of a substance is simply defined as the mass of the substance per unit volume of the substance. Mathematically, it is expressed as:

Density = mass / volume

With the above formula, we can obtain the density of the nugget of gold as illustrated below:

Mass of nugget of gold = 965 g

Volume of nugget of gold = 50 cm³

Density of nugget of gold =?

Density = mass / volume

Density of nugget of gold = 965 / 50

Density of nugget of gold = 19.3 g/cm³

Thus, the density of the nugget of gold is 19.3 g/cm³.

Oksanka [162]

Complete Question

A sample of aluminum, which has a specific heat capacity of 0.897 JB loc ! is put into a calorimeter (see sketch at right) that contains 200.0 g of water. The aluminum sample starts off at 85.6 °C and the temperature of the water starts off at 16.0 °C. When the temperature of the water stops changing it's 20.1 °C. The pressure remains constant at 1 atm. Calculate the mass of the aluminum sample.

Answer:

M=58g

Explanation:

From the question we are told that:

Heat Capacity H=0.897

Mass of water M=200g

Initial Temperature of Aluminium T_a=85.6

Initial Temperature of Water T_{w1}=16.0

Final Temperature of Water  T_{w2}=16.0

Generally

Heat loss=Heat Gain

Therefore

M*0.897*(85.6-20.1) =200*4.184*(20.1-16)

M=58g
