Answer:
Three half lives.
Explanation:
Given data:
Number of half lives passed = ?
Amount of parent isotope left = 12.5%
Solution:
At time zero = 100%
At 1st half life = 100%/2 = 50%
At second half life = 50%/2 = 25%
At third half life = 25%/2 = 12.5%
It means three half lives would passed.
Answer:
neutral groups of atoms formed by covalent bonds.
Answer:
10.69g/cm^3 or 0.0106kg/m^3
Explanation:
10.69 g/cm^3: I wrote this answer because your question doesn't mention whether volume is in cm^3 or m^3. If its in cm^3, then this is your answer.
0.0106kg/m^3: This might also be the answer if the volume is in m^3. If it is in m^3 then you have convert grams into kilograms.
So technically since you questions incomplete, the equation for measuring density is P= m/v
P= rho (density)
m= mass
v= volume
