What mass of oxygen gas contains the same number of moles as 56g of sulphur? (Relative atomic mass: S = 32, O = 16) A) 0.56g B)5
IrinaVladis [17]

Answer:

The answer is option C

Explanation:

To calculate the mass of oxygen gas we must first find the number of moles of sulphur

Molar mass = number of moles (n) / mass

n = mass / Molar mass

From the question

Molar mass (M) of Sulphur = 32g/mol

mass = 56g

n( Sulphur) = 56/32 = 1.75mol

Since the moles of oxygen and sulphur are the same

M(O2) = 16 × 2 = 32g/mol

Mass of oxygen = molar mass × moles

= 32 × 1.75

<h3>= 56g</h3>

Hope this helps you

The balanced equation below shows the products that are formed when pentane (C5H12) is combusted. C5H12 + 8O2 mc029-1.jpg 10CO2
Maru [420]

Answer: The mole ratio of oxygen to pentane for the combustion of pentane is 8 : 1.

Explanation: The given reaction is a type of combustion reaction.

Combustion reaction is a reaction in which a hydrocarbon reacts with oxygen gas to produce water and carbon dioxide gas.

For the reaction of pentane with oxygen, the balanced equation would be:

C_5H_{12}+8O_2\rightarrow 5CO_2+6H_2O

In the reaction, 1 mole of C_5H_{12} reacts with 8 moles of O_2 gas.

Thus giving us the mole ratio as

Oxygen : Pentane = 8 : 1
