We will have to use the following \[\huge \frac{ m_f }{ m_i } = \left( \frac{ 1 }{ 2 } \right)^{\left( \frac{ t }{ T^{1/2} } \right)}\] where \[T^{1/2} = \text{half life}\] \[t =\text{ time}\] \[m_f = \text{final mass}\] \[m_i = \text{initial mass}\]

So let me ask you, what are we solving for here?

Final mass
Astrophysics
  • Astrophysics
Right!

So our formula then becomes \[\huge m_f = m_i \left( \frac{ 1 }{ 2 } \right)^{\frac{ t }{ T^{\frac{ 1 }{ 2 }} }}\] right?

Now at this stage, you just need to plug in the values

and evaluate

So what u get

I think you can at least do that much.

Wait what we put for T 1/2
Astrophysics
  • Astrophysics
Don't let the 1/2 confuse you, I put it there to represent half life, that is 12.35 years

  • MTALHAHASSAN2
Oh ok
MTALHAHASSAN2
  • MTALHAHASSAN2
I am getting a very big number
Astrophysics
  • Astrophysics
\[\huge m_f = (100MG)(1/2)^{\frac{ 5.0 }{ 12.35 }}\]

Know I get 76

  • Astrophysics
Yup :)
