Answer These Questions For Me Please I Dont Have Time To Go Back And Figure This Out Rn class=

Sagot :

Answer:

Step-by-step explanation:

in 6 years we know that it will be half,  because that's what "half life" means

in 3 years it's only  loses  1/2 * 1/2 = 1/4 of it's mass

in 1 year it's only loses 1/6 * 1/2 = 1/12 of it's mass

from that we can make the formula that

current weight of radium  = Wr

Mass of radium orginal = Mo

year of time = t   ( must be in years, not days, months or weeks )

Wr = (1/12)*t* Mo
