Answer: 121.95587 g/mol
Explanation:
- The atomic mass of aluminum is 26.98154 g/mol.
- The atomic mass of phosphorous is 30.97673 g/mol.
- The atomic mass of oxygen is 15.9994 g/mol.
Therefore, the molecular mass is:
True!
Because if it has a high pressure, it can skip the liquid phase. The process is called sublimation.

Hello there!
In this case, for the given scenario, we will proceed as follows:
1. Here, we infer that the products are iron (III) hydroxide (precipitate) and calcium chloride:
2. In this step we firstly calculate the moles of both reactants, by using their molar masses 74.093 and 162.2 g/mol respectively:
Now, we calculate the moles of calcium hydroxide consumed by 0.105 moles of iron (III) chloride by using the 3:2 mole ratio between them:
Thus, we infer that calcium hydroxide is in excess as 0.189 moles are available for it but just 0.157 moles react and therefore, iron (III) chloride is the limiting reactant.
3. Here, we use the moles of iron (III) chloride we've just computed, the 2:2 mole ratio with iron (III) hydroxide and its molar mass (106.867 g/mol) as shown below:

That is a hypothesis an educated guess of what will happen
Answer:
For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit. By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.
