Answer:
The molar mass of Mg(NO₃)₂, 148.3 g/mol.
Explanation:
Step 1: Given data
- Mass of Mg(NO₃)₂ (solute): 42.0 g
- Volume of solution: 259 mL = 0.259 L
Step 2: Calculate the moles of solute
To calculate the moles of solute, we need to know the molar mass of Mg(NO₃)₂, 148.3 g/mol.
42.0 g × 1 mol/148.3 g = 0.283 mol
Step 3: Calculate the molarity of the solution
M = moles of solute / liters of solution
M = 0.283 mol / 0.259 L
M = 1.09 M

For a hydrogen atom, composed of an orbiting electron bound to a nucleus of one proton, an ionization energy of 2.18 × 10−18 joule (13.6 electron volts) is required to force the electron from its lowest energy level entirely out of the atom.
Xe is bigger:)
I hope I helped:)

<h3>What is Carbon monoxide?</h3>
Carbon monoxide, a colorless, incredibly lethal, odorless, tasteless, and flammable gas with the chemical formula CO, is a little less dense than air. Carbon monoxide is a compound made composed of one carbon atom and one oxygen atom joined by three bonds. This is the simplest molecule in the oxocarbon family. The term "carbonyl" refers to the carbon monoxide ligand in coordination complexes. It is an essential part of many industrial chemistry procedures.
Carbon monoxide plays important biological roles in all phylogenetic kingdoms.
