Magnesium and iron are metallic elements. How does a mole of magnesium compare with a mole of iron? A mole of iron has more atom
grandymaker [24]

Answer:

They both have the same number of atoms

Explanation:

The number that indicates the amount of particles in a compound is the Avogadro's number (NA).

It does not matter the mass of compound we have, If we have 1 mol we will be sure that we are talking about 6.02×10²³ particles

6.02×10²³ represents the amount of atoms in twelve grams of 12-pure carbon and it is considered a reference to measure the amount of all kinds of substances present in a given system.

The octet rule states that atoms will gain, lose, or share valence electrons to get a full outer shell (orbital). Explain in you
bezimeni [28]

Answer:

In covalent bonding, the octet rule is important because sharing electrons gives both atoms a full valence shell. As a result, each atom can consider the shared electrons to be part of its own valence shell.

Sati [7]

Answer:

The peak at mass 100 with a 8% relative abundance is the molecular ion peak

Explanation:

Molecular ion peak has the highest charge to mass ratio,

Mass of 100 is same as mass to charge ratio =100

How many grams are there in 1.1 x 1027 molecules of water (H2O)?
Nezavi [6.7K]

Answer:

C) 3.3 x 104 grams

Explanation:

1 mole of water contains 6.02 × 10^23 atoms

1.1 × 10^27 atoms will contain;

1.1 × 10^27 ÷ 6.02 × 10^23

= 0.1827 × 10^( 27 - 23)

= 0.1827 × 10^(4)

= 1.827 × 10³ moles of water.

To convert mole to mass in grams, we use the formula;

mole (n) = mass (m) ÷ molar mass (MM)

Molar mas of water (H2O) = 1(2) of H + 16 of O = 18g/mol

mole = mass/molar mass

1.827 × 10³ = mass / 18

mass = 1.827 × 10³ × 18

mass = 32.886 × 10³

mass = 3.286 × 10⁴

mass = 3.3 × 10⁴ grams
