Compare 1 mole of H2, 1 mole of O2 and 1 mole of F2

likoan [24]

Explanation:

(a) As per the mole concept, one mole of any atom contains $6.022 \times 10^{23}$ atoms or molecules, that is, Avogadro's number of atoms.

Therefore, 1 mole of $H_{2}$ = $2 \times 6.022 \times 10^{23}$ molecules

= $1.2044 \times 10^{23}$ molecules

1 mole of $O_{2}$ = $2 \times 6.022 \times 10^{23}$ molecules

= $1.2044 \times 10^{23}$ molecules

1 mole of $F_{2}$ = $2 \times 6.022 \times 10^{23}$ molecules

= $1.2044 \times 10^{23}$ molecules

Hence, there are equal number of molecules present in the given atoms.

(b) Mass of each given atom will be calculated as follows.

Mass = no. of moles × molar mass

As one molecule of $H_{2}$ contains 2 atoms of hydrogen.

So, mass of 1 mole of $H_{2}$ = $2 mol \times 1.008 g/mol$

= 2.016 g

mass of 1 mole of $O_{2}$ = $2 mol \times 15.999 g/mol$

= 31.996 g

mass of 1 mole of $F_{2}$ = $2 mol \times 18.998 g/mol$

= 37.996 g

Thus, we can conclude that $F_{2}$ has the greatest mass.

A certain chemical contains 46.30% chlorine, 47.05% carbon, 6.63% hydrogen. What is the molecular formula of the compound? The m

RoseWind [281]

Answer:

C6H10Cl2

Explanation:

Convert mass % to mass

100g of the compound contains from each elements: 46,3g Cl; 47,05g C and 6,63g H

Molar mass

Cl = 35.5 g/mol

C = 12 g/mol

H = 1 g/mol

Find the number of moles:

Chlorine: 46.4g /35.5g/mol = 1,3 moles

Carbon: 47,05g/12 g/mol = 3,92 moles

hydrogen: 6,63g/1g/mol = 6,63 moles

Molar fraction:

Cl = 1,30/ 1,30 = 1

C = 3,92/ 1,30 = 3,01

H = 6,63/ 1.30 = 5,01

C3H5Cl = 76,5 g/ mol x 2 = 153 g/ mol

So multiply the molecular formula by two = C6H10Cl2
