HELP ASAP I WILL GIVE BRAINLIST!! Determine the empirical formula of a compound containing 40.6 grams of carbon, 5.1 grams of hydrogen, and 54.2 grams of oxygen. In an experiment, the molar mass of the compound was determined to be 118.084 g/mol. What is the molecular formula of the compound?

For both questions, show your work or explain how you determined the formulas by giving specific values used in calculations. (10 points)

The empirical formula of the compound is: C2H3O2

The molecular formula of the compound is: C4H6O4

Explanation:

Step 1: Data given

A compound contains 40.6 grams Carbon, 5.1 grams of hydrogen and 54.2 grams of oxygen

The molar mass = 118.084 g/mol

Molar mass of carbon = 12 g/mol

Molar mass of Hydrogen = 1.01 g/mol

Molar mass of oxygen = 16 g/mol

Step 2: Calculate moles

Moles = mass / molar mass

Moles C = 40.6 grams / 12.0 g/mol = 3.38 moles

Moles H = 5.1 grams / 1.01 g/mol = 5.05 moles

Moles O = 54.2 grams / 16g/mol = 3.39 moles

Step 3: Calculate mol ratio

We divide by the smallest amount of moles

C: 3.38/3.38 = 1

H: 5.05 / 3.38 = 1.5

0: 3.39/3.38 = 1

The empirical formula is C2H3O2

The molar mass of this formula is 2*12+3*1.01+2*16 = 59.03 g/mol

Step 4: Calculate molecular formula

118.084 / 59.03 = 2

The molecular formula = 2*(C2H3O2) = C4H6O4

what's the question?

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
