Answer:
c. 12,500
Explanation:
Original number of atoms = 100,000 atoms
Half- life = 10min
Unknown:
The number of atoms that will remain after 10min = ?
Solution:
The half - life is the time taken for half of a radioactive substance to decay by half.
Time taken Number of atom half life
10min 100000 _
20min 50000 1
30min 25000 2
40min 12500 3
Answer:
1.22gcm³
Explanation:
D = mass/ volume
Mass=1.840kg = 1,840g
1000g = 1kg
1.840kg= x(g)
X(g) = 1.840/1000
= 1840g
Volume = 0.0015m³= 1,500cm³
1m³= 1000,000cm³.
0.0015m³= x(cm³)
X(cm³) = 1000,000×0.0015
X(cm³)= 1500.
Since density is mass/volume, now impute your data's
D=m/v
D=1840/1500
1.22g/cm³
