The molecular formula of the ethylene glycol is C₂H₆O₂.

From the question given above, the following data were obtained:

  • Empirical formula = CH₃O
  • Molar mass of compound = 62 g/mol
  • Molecular formula =?

Molecular formula = empirical × n = molar mass

[CH₃O]n = 62

[12 + (3×1) + 16]n = 62

31n = 62

Divide both side by 31

n = 62 / 31

n = 2

Molecular formula = [CH₃O]n

Molecular formula = [CH₃O]₂

Molecular formula = C₂H₆O₂

Determine the empirical formula. a 3.880g sample contains 0.691g of magnesium , 1.84 g of sulfur , and 1.365 g of oxygen .
Aliun [14]

Answer:

Mg S2 O3

Explanation:

.691 g of Mg  is .284 mole

1.84 g of S    is .5739 mole

1.365 g of O is  .8531 mole      you can see the ratio is ~  1 :2 :3

                                                        Mg S2 O3

Ryan and Abigail are conducting an experiment. They place six ice cubes into a beaker and find the combined mass. They allow the
JulijaS [17]

The mass of the ice cubes and the water will be equal because the same amount of matter is in the beaker.

Matter is anything that has mass and occupy space. All substances are composed of matter. According to the law of conservation of mass, matter can neither be created nor destroyed but can be converted from one form to another.

Since mass is the quantity of matter in a substance, the mass of the ice cubes and the water will be equal because the same amount of matter is in the beaker.

If an object has a mass of 180 g and a density of 6 g/cm^3, what is the volume of the object?
cupoosta [38]

Answer:

<h3>The answer is 30 cm³</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density} \\

From the question

mass = 180 g

density = 6 g/cm³

We have

volume =  \frac{180}{6}  \\

We have the final answer as

<h3>30 cm³</h3>

Hope this helps you
