Answer:

from the pic:

empirical \: formular :  \:  \: C  _{2}H _{3}O _{2}

since molar mass is 118.084 g/mol;

(C  _{2}H _{3}O _{2}) _{n} = 118.084 \\ C  _{2n}H _{3n}O _{2n} = 118.084 \\(12 \times 2)  _{n} + (1 \times 3) _{n} + (16 \times2 ) _{n} = 118.084 \\ 24_{n} + 3_{n} + 32_{n} = 118.084 \\ 59_{n} = 118.084 \\ n = 2

{ \boxed{ \bf{molecular \: formular :  \: C  _{4}H _{6}O _{4}}}}

It is an aldehyde with structure ( second pic )

How many atoms are in 0.500mol of calcium?
creativ13 [48]

Answer:

3.01×10²³ atoms of calcium

Explanation:

number of moles = number of atoms/Avogadro's constant

n = N/NA

N = n×NA = 0.500 mol×6.02×10²³ mol^-1

N = 3.01×10²³ atoms of calcium

One molecule of sucrose is burned with oxygen to make carbon dioxide and water.

Disaccharide sugar sucrose is composed of glucose and fructose. It is produced naturally by plants and is the main component of white sugar. C₁₂H₂₂O₁₁ is the chemical formula for it.

Extraction and refining sucrose for human use can be done from either sugarcane or sugar beet. Raw sugar is created from crushing the cane, which is consistently delivered to other sectors to be refined into pure sucrose. Sugar mills generally are located in the tropical regions near the sugarcane plantations.

<em>                    C₁₂H₂₂O₁₁ + 12O₂  →  12CO₂ + 11H₂O</em>

When one molecule of sucrose is burnt, we get 12 carbon dioxide molecules.

To learn more about sucrose,
