Here is another simple explanation:
First convert the mass in kg to g ( 1kg=1000g). Now 18g of H20 is equivalent to 1 mole. Hence, 1000g of it would be equal to 1000/18 moles. This comes out be 55.55 moles. Thus 1 kg of water or ice has 55.55 moles of H20.
Thank you sir for your explanation. I was in fact, confused by the following answer to the above problem, which I found in a book :-
" The eye lens is a convex lens, which converts any light coming from a virtual object into a real object by focusing the light rays to form a real image, which is...
[b]1. Homework Statement
Q: How does our eye see virtual images, considering that no light is emmited by a virtual image and our eye can see anything only when light from it reaches the eye?
Examples: Image by a plane mirror, concave lens, convex mirror and by convex lens and concave...
Please provide me with some help in optics. This doubt is in relation to the use of sign conventions in optics. Whenever we prove anything in optics, say for example, when we prove the mirror formula or the lens formula or the lens-maker's formula, we apply the sign conventions in the derivation...
