I'm not sure what "mole" is but I am gonna assume molar so "Molar" mass is the mass of a given substance divided by the amount of that substance, measured in g/mol. For example, the atomic mass of titanium is 47.88 amu or 47.88 g/mol. In 47.88 grams of titanium, there is one mole, or 6.022 x 1023 titanium atoms.
have a good day hope this helps
Answer:
ΔT = 0.61°C
Explanation:
That's the formula for the colligative property of freezing point depression:
ΔT = m . Kf . i
AlCl₃ is a ionic salt that be dissociated:
AlCl₃ → Al³⁺ + 3Cl⁻ i = 4
In solution, we can have 4 moles of ions, 1 mol of Al³⁺ plus 3 moles of chloride. (We assume 100 %ionization)
Let's replace data: ΔT = 0.082 m . 1.86 °C/m . 4
ΔT = 0.61°C
The one created by mandeleev is not in order of increasing the atomic number
Answer:
Relative and average atomic mass both describe properties of an element related to its different isotopes.
Explanation:However, relative atomic mass is a standardized number that's assumed to be correct under most circumstances, while average atomic mass is only true for a specific sample.

<h3>What is a conjugate acid and base pair?</h3>
An acid-base pair that differs by one proton is referred to as a conjugate pair. A conjugate acid-base pair is a pair of substances that can both absorb and donate hydrogen ions to one another. A proton is added to the compound to create the conjugate acid, and a proton is taken out to create the conjugate base. When a proton is supplied to a base, a conjugate acid is created, and vice versa when a proton is taken away from an acid, a conjugate base is created.
