The number of moles in 32.5g of aluminum chloride is approximately 0.250 moles.
Sorry I don’t know the answer I am just Thea answer is whatever the person you answer Rushdie you answer the answer negative and I am trying something I am so sorry
Answer:
2 m apart
Explanation:
Two cars of mass 3000 kg are 2 m apart what is the force of gravity between them using The universal law of gravitation
To find molarity
We need no.of moles and solution in liter
Given data is in grams and ml
We have to convert it in required units
For no.of moles use formula
No.of mole=mass in gram / molar mass
Mass in gram = 29.1g
Molar mass = 160.4374g/mol calculated by adding the atomic wight of all atoms in LiClO4.3H2O
Atomic weight
Li= 6.941
Cl= 35.453
O= 15.9994
H= 1.00794
Now put it in mol equation
No.of mole = 29.1/160.4374
= 0.181mol of solute
Now convert solution in L from ml
235ml = 235/1000 = 0.235L
Now put these values in molarity formula
Molarity= 0.181/0.235
= 0.77M solution
