What percent of a present amount of radioactive radium (226Ra) will remain after 1200 years? The half life of 226Ra is 1599 year
sp2606 [1]

Answer:

59.44%

Step-by-step explanation:

<em>M_{R} = \frac{M_{O} }{2^{n} }</em>

<em>n=\frac{t}{t\frac{1}{2} }</em>

<em>Where M_{R} = mass remaining</em>

<em>M_{O} =original mass.</em>

<em>t= time </em>

<em>t\frac{1}{2} =half life</em>

t\frac{1}{2} =1599,  t= 1200, M_{O} =226,  M_{R} =?

n=\frac{1200}{1599}

n= 0.750469

M_{R} = \frac{226}{2^{ 0.750469} }

M_{R} =134.3367amu

percentage of mass remaining = \frac{134.3367amu}{226amu} *100%

                                                   = 59.44%
