What is the empirical formula of a phosphoric acid that contains 0.3086 g of hydrogen, 3.161 g of phosphorus, and 6.531 g of oxygen?

The empirical formula is

Explanation:

Given:

Mass of H = 0.3086 g

Mass of P = 3.161 g

Mass of O = 6.531 g

Step 1 : convert given masses into moles.

Moles of H=

Moles of P=

Moles of O =

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For H=

For P=

For O =

The ratio of H:P:O= 3: 1: 4

Hence the empirical formula is

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
