Answer:
Yes , 5 mole of Iron Oxide has mass of 798.5 g
Explanation:
Formula of iron oxide:
Atomic mass of Fe = 55.84 amu
Atomic mass of O = 15.99 amu
Molar mass of Fe2O3 = 2(atomic mass of Fe) + 3(atomic mass of O)
= 2(55.84) + 3(15.99)
=111.68 + 47.97
= 159.69 g/mol
<u>Molar mass</u> always equal to <u>1 mole</u> of the substance.
1 mole = 159.69 g
5 mole =
= 798.45 g
Hello Mate!
Well, there are many definitions and descriptions of isolated systems, and here are some of them:
1. It can be a physical system which is located very very far from all other systems, so there is absolutely no interaction between them, thus making it isolated.
2. It can be a thermodynamic system with rigid walls, which prevents mass and energy to pass through.
