Cobalt-63 has a half-life of 5.3 years. If a pellet that has been in storage for 15.9 years contains 40.0g of Cobalt-63, how muc
Cerrena [4.2K]

Answer:

320 g  

Step-by-step explanation:

The half-life of Co-63 (5.3 yr) is the time it takes for half of it to decay.  

After one half-life, half (50 %) of the original amount will remain.  

After a second half-life, half of that amount (25 %) will remain, and so on.  

We can construct a table as follows:  

  No. of               Fraction         Mass

half-lives   t/yr   Remaining   Remaining/g

      0        0              1

      1         5.3           ½

     2        10.6           ¼

     3        15.9           ⅛                 40.0

     4        21.2           ¹/₁₆

We see that 40.0 g remain after three half-lives.

This is one-eighth of the original mass.

The mass of the original sample was 8 × 40 g = 320 g

_____ is a measure of the average kinetic energy of a gas. Density Enthalpy Pressure Temperature
Fiesta28 [93]

Answer:

Temperature

Explanation:

  • Temperature is a measure of the average kinetic energy of the particles in a sample of a gas.
  • Kinetic energy is the energy possessed by an object because of its motion. As an object absorbs heat the particles move faster so the average kinetic energy and therefore the temperature increases.
  • When the temperature of a body or an object is increased and hence the heat, there is more movement or vibration of particles which translates to more kinetic energy.
