As Molarity is given by,
Molarity = moles / volume ------(1)
Data Given:
mass of water = 5 Kg = 5000 g
moles = 5 moles
Solution:
As we know that volume is related to mass as,
Volume = mass / density
Putting values,
Volume = 5000 g / 1 g/cm³
V = 5000 cm³
Now, Putting value of volume and moles in eq. 1,
M = 5 mol / 5000 cm³
M = 0.0001 mol/cm³
or,
M = 1 mol/dm³
It is cheap, lightweight and extremely malleable.
Answer:
I had the same question and I put a total lunar eclipse.
Explanation:
A total lunar eclipse would be less widely visible because, in a partial lunar eclipse the moon only has to partly be in the Earth's shadow.
I don't know if this is helpful or not, but this is what I put if you still needed it.

In most atoms, electrons occupy a zone exterior to the nucleus.
<h2>Answer:</h2>
Option A is correct;
A.) The atoms are arranged differently in each molecule
<h3>Explanation:</h3>
Water and hydrogen peroxide are made of the same elements: oxygen and hydrogen. However, hydrogen peroxide (H2O2) has 1 more oxygen than water (H2O).
Hydrogen peroxide is very unstable and breaks down readily into water and a single oxygen molecule.
And also the arrangement of atoms is different in each molecule.
