Given data:
Mass of cesium chloride CsCl (m) = 52.3 g
Mass of water (mh2O)= 60.0 g
Volume of the solution (V) = 63.3 ml
Step 1: Calculate the number of moles of CsCl
Molar mass of CsCl = 168.36 g/mol
Mass of CsCl = 52.3 g
# moles = mass/molar mass = 52.3 g/168.36 g.mol-1 = 0.3106 moles
Step 2: Volume of solution in Liters
1000 ml = 1 liter
therefore, 63.3 ml corresponds to : 63.3 ml * 1 L/1000 ml = 0.0633 L
Step 3: Calculate molarity of CsCl
Molarity = moles of CsCl/volume of solution
= 0.3106 moles/0.0633 L = 4.91 moles/L
Molarity = 4.91 M
Answer:
The number of carbon atoms is twice the number of magnesium atoms
The Earth's core is the part of Earth in the middle of our planet. It has a solid inner coreand a liquid outer core.
Hey there!:
Mass = 2.98 g
Volume = 2.12 L
Therefore:
Density = mass / volume
Density = 2.98 / 2.12
Density = 1.405 g/L
There would be about 1.67 x 10^25 oxygen atoms and about 3.34 x 10^25 hydrogen atoms.
