Answer:
74.10g/mol
Explanation:
The mass of one mole of Ca(OH)₂ is the molar mass of the compound.
To solve this problem, we add the atomic masses of the species in the compound;
Atomic mass of Ca = 40.078g/mol
O = 15.9994g/mol
H = 1.0079g/mol
So;
Molar mass = 40.078 + 2(15.9994 +1.0079 ) = 74.10g/mol
<span>The answer would be: The two substances are not the same because the property that is independent of the amount of the sample is different.<span>
The two substances has different solubility which is </span></span>36 g/mL and <span>180 g/mL. The same kind of molecule should have same density and solubility, regardless the mass of the sample. In this case, the substances are not same since it has different solubility.</span>
