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 number of oxygen molecules are required to produce 0.22 g of CO2 according to the reaction?
zmey [24]
The number of moles for co2=mass(g)/molar mass
n=.22/44=.005 mole of CO2
from the equation we see the relationship between the moles of co2 and O2 and we find that they have the same number of moles
So we need .005mole of O2
Multiple the number of moles with avogadro’s number to know the number of O2molecules
.005x6.022 x10^23

if the particles formed through fission have less mass than the starting material has the laaw of conversation of energy been br
Alexxandr [17]

The law of conservation of energy has not been broken, provided energy is released from the fission process.

<h3>What is the law of conservation of energy?</h3>

The law states that the total energy of a process is conserved. That is, the total energy or mass of a system before and after undergoing processing remains the same. However, some of the mass/energy can be converted to another form.

When a material undergoes fission, the sum total of the mass of the particles formed should be equal to the mass of the starting materials, provided that all other things remain the same.

However, if energy is released from the fission process, it means that some of the mass of the starting materials has been converted to energy and released to the environment.
