How many mol of sodium phosphate will form when 0.275 mol of sodium bromide react with phosphoric acid? The reaction is shown below. 3 NaBr + H3PO4 --> Na3PO4 + 3 HBr

Explanation:

Firstly balance the chemical reaction,

  →  

Molecular weight of =103g/mole;

Molecular weight of =164g/mole;

Moles are:

Number of mole of =0.275

From the balanced equation,

3 mole of gives 1 mole of  

1 mole of gives 1/3 mole of

Hence;

0.275 mole of will produce mole of  

Hence,

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
