Answer:
Radium
Explanation:
It has the highest atomic number so it would have more shells, making it larger than the others.
1. 1 M , 2 M , 1 M
2. 10 mol , 0.1 mol , 0.5 mol
3. 0.5 L , 6.6 L , 5/21 L
M = mol/L
Answer : C) 5.0 x 10^-3 M
if the concentration of Ba(OH)2 is 2.5 x 10^-3 M
then the OH- concentration is twice this so your answer is C.
Answer:
The answer to your question is density = 635.3 g/ml (check the units)
Explanation:
Data
density = ?
volume = 85 ml
mass = 54 kg
Density is a physical property that relates the mass of an object and its volume.
The unit of this property are g/ml or kg/m³
In this problem, I will calculate the density in g/ml
Formula
density = mass/ volume
-Substitution
density = 54000 / 85
-Simplification
density = 635.3 g/ml
