Question

how many grams of carbon are there in 83.5 gram of formaldehyde ch2o​

Answer 1

$\huge\mathtt\red{Answer:}$

• Formaldehyde is a covalent chemical compound consisting of carbon, hydrogen and oxygen atoms, according to the given molecular formula:
• Formaldehyde is a covalent chemical compound consisting of carbon, hydrogen and oxygen atoms, according to the given molecular formula:CH2OCH2O
• Formaldehyde is a covalent chemical compound consisting of carbon, hydrogen and oxygen atoms, according to the given molecular formula:CH2OCH2OThe compound sample mass is 83.5 grams. If we multiply this compound mass by the given carbon mass percent of 40.0% in decimal form, then we get the mass of carbon atoms inside the sample:
• Formaldehyde is a covalent chemical compound consisting of carbon, hydrogen and oxygen atoms, according to the given molecular formula:CH2OCH2OThe compound sample mass is 83.5 grams. If we multiply this compound mass by the given carbon mass percent of 40.0% in decimal form, then we get the mass of carbon atoms inside the sample:0.400×83.5 g=33.4 g

Answer 2

Answer:

Mass Percent Composition:

Every chemical compound contains some fixed proportion of two or more different constituent atoms. A common example is the water molecule

H

2

O

, which is also an example of a molecular formula for a compound. The molecular formula for a particular chemical compound is always written the same. This means that for a given mass of a compound, it will always contain the same contributing mass fractions of each constituent element. This statement is the basis for describing the composition of a compound as a set of mass percent values.
