Trihydrate - basically 3 molecules of water. Unless you're referring to the molecule 3H2O used in measuring the total body water in the case it tritiated water.
Density = mass/volume = 80 g/10cm³ = 8 g/cm³
Answer:
5.35×10²⁴ atoms of Li
Explanation:
To solve this we apply this rule of three:
We know that 1 mol contains 6.02×10²³ atoms
Therefore, 8.9 moles must contain (8.9 . 6.02×10²³) / 1 = 5.35×10²⁴ atoms
One mol is the amount of substance containing as many elemental entities as atoms, which are contained in 12 g of the C¹² isotope
In conclussion 6.02×10²³ atoms of C¹² isotope weighs 12 g
Answer : The molecular formula of benzoyl peroxide is
Explanation :
Empirical formula : It is the simplest form of the chemical formula which depicts the whole number of atoms of each element present in the compound.
Molecular formula : it is the chemical formula which depicts the actual number of atoms of each element present in the compound.
For determining the molecular formula, we need to determine the valency which is multiplied by each element to get the molecular formula.
The equation used to calculate the valency is :
As we are given that the molar mass of compound is, 0.242 kg/mol.
Molecular mass = 0.242 kg/mol = 242 g/mol (1 kg = 1000 g)
The empirical mass of = 7(12) + 5(1) + 2(16) = 121 g/eq
Molecular formula = = =
Thus, the molecular formula of benzoyl peroxide is
