Question

A molecule of antifreeze, ethylene glycol, has the formula c2h4(oh)2. how many atoms are there in one molecule of antifreeze?

Answer 1

the total atoms in one molecule of antifreeze = 2 + 6 + 2 = 10

Step-by-step explanation:

The number of atoms in the given ethylene glycol molecule can be calculated from its molecular formula.

The molecular formula is :
`C_(2)H_(4)(OH)_(2)`

The subscripts represent the multiplicity of the atoms present

Here the subscript on carbon = 2 so there are two carbon atoms

the subscript on hydrogen = 4 and two on OH, so the total hydrogen atoms = 6

The subscript on oxygen =2 so the total oxygen atoms= 2

Hence the total atoms in one molecule of antifreeze = 2 + 6 + 2 = 10

Answer 2

Answer is: there are ten atoms in one molecule of antifreeze.
One molecule of ethylene glycol (C₂H₄(OH)₂) has two carbon atoms, six hydrogen atoms (4 + 2 · 1) and two oxygen atoms (2 · 1). So there are:
2 + 6 + 2 = 10 atoms.
Ethylene glycol (C₂H₄(OH)₂) is an odorless, sweet-tasting, colorless viscous liquid.
