MFe: 56 g/mol
..........
56g ----- 1 mol
5g ------- X
X = 5/56 = 0,089 moles of Fe
56g ----- 6,02×10²³ atoms
5g ------- X
X = (5×6,02×10²³)/56
X = 0,5375×10²³ = 5,375×10²² atoms of Fe

Answer:
The primary function of chemical nomenclature is to ensure that a spoken or written chemical name leaves no ambiguity concerning which chemical compound the name refers to: each chemical name should refer to a single sub
Answer:
The density is 10.25
Explanation:
From the question we are given that the lattice spacing nm
V = ×
= 0.1628
zinc blende lattice has 4 atom per unit cell.
This means that 4 atoms is contained in 0.15056
Density of the cubic unit in terms of atom is given as =
=26.565
For plane (110) the spacing between the cubic unit in the crystal denoted by is given as = Where a is the lattic spacing = 0.546
= = 0.376 nm
The density of the lattice in (110) plane =26.565 × 0.386 nm
= 10.25
The balanced chemical
reaction will be:
<span>2C6H6 + 15O2 = 12CO2 + 6H2O</span>
We are given the amount of benzene to react with oxygen gas.
This will be our starting point.
<span>10.47 g C6H6 ( 1 mol C6H6 / 78.1074 grams C6H6) (15 mol O2/2 mol C6H6 ) (
32 g O2 / 1 mol O2) = 32.1711g O2</span>
