Answer:
40.32L
Explanation:
So we know that 22.4 Liters is one mole of a gass so we can set up an equation to test that
1mole 1.8mole
_____ = _____
22.4L x
and then cross multiply so you get 40.32L
Answer : The correct option is, (A) 0.109 M 
Solution : Given,
Mass of = 17 g
volume of solution = 974 ml
Molar mass of = 159.609 g/mole
Molarity : It is defined as the number of moles of solute present in one liter of solution.
Formula used :
where,
w = mass of (solute)
M = molar mass of
= volume of solution in liter
Now put all the given values in the above formula, we get the molarity of solution.
Therefore, the molarity of the solution is, 0.109 M
Explanation:
An atom is made up of:
- Protons which are the positively charged particles
- Electrons are negatively charged
- Neutrons carry no charges.
Atomic number is the number of protons in an atom.
To find the nuclear charge:
We use the effective nuclear charge formula:
Effective nuclear charge = Atomic number - number of shielding electrons(non-valence electrons)
The shielding electrons are the non-valence electrons in the inner orbitals.
For example:
Ne:
atomic number = 10
Effective nuclear charge = 10 - (2) = 8+
Number of non-valence electrons is 2
The effective nuclear charge is 8+
Overall charge:
Charge = number of protons - number of electrons
For neutral atoms, the overall charge is zero as the number of protons and electrons are the same.

If the mass of both the reactants is 10kg then the mass of the products also equals 10kg.
It is due to the law of conservation of mass.
Mass can neither be created nor be destroyed.
