The average mass of all of

the isotopes of a substance Isotopes are atoms from

the same element

(therefore containing the

same number of protons)

which have different

numbers of neutrons.

1. Multiply the mass of each

isotope by the % of the

isotope

2. Add the products

Sulfur has three main isotopes.

95% is Sulfur-32, 4% is Sulfur-34,

and 1% is Sulfur

- 33.

So 32.09 amu

Jobisdone [24]

Answer:

Option 2. One mole of methane gas reacts with two moles of dioxygen gas, producing one mole of carbon dioxide gas and two moles of gaseous water.

Explanation:

The clue is in the stoichiometry of the reaction:

1 CH₄(g) + 2 O₂(g) → 1 CO₂(g) + 2 H₂O(g)

In any chemistry reaction, the stoichiometric coefficients are moles; moles of reactants to produce moles of products

RUDIKE [14]

Answer:

Explanation:

a) Volume of the gas nRT / P

= 1,04 X 8.3 X 298 / 11 X 10⁵ m³

= 233.85 x 10⁻⁵ m³

= 233 x 10⁻² L

2.33 L

P₁V₁ / T₁ =P₂V₂/T₂

(11 X 2.33) / 298 = (1 X 24.2) / T

T = 281.37 K

= 8.37 degree

b ) w = p x change in volume

= 10⁵ x ( 24.2 - 2.33 ) x 10⁻³ J

= 21.87 X 10² J

2187 J

q  = n x Cp x (25 - 8.37 )

= 1.04 x 35.66x 16.63 J

= 616.65 J

ΔU = Q - W

= 616.65  - 2187 J

= - 1570.35 J

=
