Answer:
125g × 1 mol/16 grams = 7.81 × avogadros #
Answer = B = Neutrons and Mass Number
Isotopes are defined as those atoms which have same atomic number but different atomic masses.
Atomic mass is basically the number of protons and neutrons present in an atom.
Atomic number is the number of protons present in an atom.
So, in isotopes the number of protons are same but the number of neutrons vary due to which atomic masses also vary.
In given three isotopes, all have same number of protons but different number of neutrons.
i.e.
H-1 = 1 P + 0 N = 1 u (Proton)
H-2 = 1 P + 1 N = 2 u (Deuterium)
H-3 = 1 P + 2 N = 3 u (Tritium)
Hence, it is clear that the number after H shows a change in number of neutrons and mass number.
Answer:
1.20 M
Explanation:
Convert grams of Na₂CO₃ to moles. (50.84 g)/(105.99 g/mol) = 0.4797 mol
Molarity is (moles of solute)/(liters of solvent) = (0.4797 mol)/(0.400 L) = 1.20 M
Answer: because it consists of more than one element, which are hydrogen and oxygen in a covalent bond.
The name of the configuration management procedure that involves the collection of information about a system under normal operating conditions is Baselining.
<h3>What is Baselining?</h3>
Baselining is a management process used to analyze a collection of information about a particular system.
This procedure (Baselining) is well known to analyze computer performance in a given network.
In conclusion, the name of the configuration management procedure that involves the collection of information about a system under normal operating conditions is Baselining.
