The half-life of Radium-226 is 1590 years. If a sample contains 500 mg, how many mg will remain after 2000 years? Preview mg Giv
d1i1m1o1n [39]

Answer:

a_{n}=209.09 mg

Step-by-step explanation:

given: material= radium

half life= 1590 years

initial mass a_{0} =500mg

we know that to calculate the amount left we use

a_{n} = a_{0}\left ( 0.5\right )^{n}

n=\frac{2000}{1590} = 1.2578

therefore

a_{n} = 500\times0.5^{1.2578}

a_{n}=209.09058407921 mg

a_{n}=209.09 mg amount left after 2000 years
