Given the following: 30 grams of H3PO4, find the number of moles

Number of mole of H₃PO₄ = 0.306 mole

Explanation:

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

Mass of H₃PO₄ = 30 g

Number of mole of H₃PO₄ =?

Next, we shall determine the molar mass of H₃PO₄. This can be obtained as follow:

Molar mass of H₃PO₄ = (3×1) + 31 + (4×16)

= 3 + 31 + 64

= 98 g/mol

Finally, we shall determine the number of mole in 30 g of H₃PO₄ as follow:

Mass of H₃PO₄ = 30 g

Molar mass of H₃PO₄ = 98

Number of mole of H₃PO₄ =?

Mole = mass / molar mass

Number of mole of H₃PO₄ = 30 / 98

Number of mole of H₃PO₄ = 0.306 mole

why is cellular respiration important for homeostasis?

it changes food into energy that the organism can use.

which of the following is most likely to happen if a cell is not able to divide?

the cell will not be replaced when it is damaged.

explanation:

"the periodic table is arranged in order of atomic number."
