Aspirin is the analgesic acetylsalicylic acid C9H8O4. What is the coefficient of oxygen in the balanced equation for the combust
swat32

Answer:

Option g. (9)

Explanation:

Let's think the equation. In a combustion, the oxygen is the reactant and the products are CO₂ and water. So the reaction must be:

C₉H₈O₄  +  O₂  →  CO₂  +  H₂O

If balance the equation would find out that the coefficient of oxygen is 9  .

C₉H₈O₄  +  9O₂  →  9CO₂  +  4H₂O

Trava [24]

Answer:

0.779 moles.

Explanation:

Mass of chlorine/number of moles = molar mass of chlorine.

Molar mass of chlorine = (35.5*2)

= 71 g/mol.

Mass = 55.3 g of chlorine.

Number of moles = 55.3/71

= 0.779 moles.

Calculate the molar mass of powdered fruit drink mix, made from sucrose (c12h22o11). appreciate it.
schepotkina [342]

molar mass of sucrose is 342 g/mol.

Concept:

It is the substance's molecular mass. M is the abbreviation for it, and g/mol is the standard unit for measuring molar mass.

Given:

Sucrose (C12H22O11)

Find:

Calculate the molar mass of the powdered fruit drink mix, made from sucrose (C12H22O11).

Solution:

The molar mass of carbon = 12 g/mol

The molar mass of hydrogen = 1 g/mol

The molar mass of oxygen = 16 g/mol

Thus, the molar mass of sucrose can be calculated as:

C12H22O11 12 C + 22 H + 11 O

= 12 12 g/mol + 22 * 1 g/mol + 11 * 16 g/mol

= 144 g/mol + 22 g/mol + 176 g/mol = 342 g/mol

Therefore, the molar mass of sucrose is 342 g/mol.

Hence, the molar mass of the powdered fruit drink mix, made from sucrose

Hence, the molar mass of the powdered fruit drink mix, made from sucrose(C12H22O11) is 342 g/mol.
