The main differences between a plant cell and animal cells is that plant cells have more of a rectangular shape because the cell wall is more rigid. While animal cells have more of a circular or irregular shape because they don't have a cell wall. Plant cells usually have one or more large vacuoles, while animal cells have smaller vacuoles if any are present.

Calculate the number of moles 230 g of C2H5OH 560 g of C2H4 0.640 g of SO2

Naddik [55]

Mass of C = 12g
mass of H = 1g
mass of O = 16g
mass of C2H5OH = 46g = 1 mole

1 mole of C2H5OH ------------ 46g
x moles of C2H5OH ----------- 230g
x = 5 moles of C2H5OH

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
mass of C = 12g
mass of H = 1g
mass of C2H4 = 28g = 1 mole

1 mole of C2H4 -------------- 28g
x moles of C2H4 ------------- 560g
x = 20 moles of C2H4
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
mass of S = 32g
mass of O = 16g
mass of SO2 = 64g = 1 mole

1 mole of SO2--------------------- 64g
x mole of SO2 -------------------- 0,64g
x = 0,01 moles of SO2
