Answer:

0.465

Explanation:

To find the volume of a substance, divide the mass by the density.

M/D = V

10.0 / 21.5 = 0.4651163

Then round to 3 significant figures: and the density is 0.465

Determina el numero de masa para el paladio en la siguiente tabla:*
Damm [24]

The concept of atomic masses we can find that the correct answer is:

       c) 101

The atomic mass or mass number of an element is the sum of its protons plus the neutrons that are in the atomic nucleus, the electrons are not taken into account because they have a mass much lower than the masses of protons and neutrons.

   

In the table they indicate that there are 46 protons and 55 neutrons, therefore

          M = #_ {protons} + #_ {neutrons}

          M = 46 +55

          M = 101

In conclusion using the concept of atomic masses we find that the correct answer is:

c) 101
