Answer:
615ml
Explanation:
Vol(ml) = (gms solute)/[(Molar Answer => Conc)(formula Wt solute))] = (100g)/{(1.4M)(116g/mol)} = 0.615L = 615ml.
<span>The answer is - a. Alkali Metal.
</span>They react violently with water to form alkaline solutions. This is because they all have 1 electron in their outer shell and losing 1 electron allows them to have full outer shells, and achieve stability.

Answer: 43.
Explanation:
Mass number is the sum of protons and neutrons of an atom.
The number of prortons is the atomic number, so you can write:
Mass number = atomic number + number of neutrons. From which you get;
number of neutrons = mass number - atomic number = 80 - 37 = 43
All the atoms of a given element have the same number of protons. That is why the number of protons idenfies the elements and is called atomic number.
The number of neutrons of a given element may be different for different atoms of the same element.
The atoms of an element that have different number of neutrons are called isotopes. So, different isotopes of the same element have same atomic number but different mass number.
The description of an ideal gas is as follows:
- They have a small mass
- They have a small volume
- They have no intermolecular forces
<h3>WHAT IS AN IDEAL GAS?</h3>
An ideal gas is a theoretical gas composed of many randomly moving particles that do not engage in any inter-particle interactions.
An ideal gas obeys all the gas laws and possess the following characteristics:
- They have a small mass
- They have a small volume
- They have no intermolecular forces
