The molecular weight of phosphoric acid, H 3 PO 4 , is 97.99 * g/(mol) What is the mass, in grams, of 0.00948 mol of phosphoric acid?

The molecular weight of phosphoric acid H 3 PO 4 is 9799 gmol What is the mass in grams of 000948 mol of phosphoric acid class=

Respuesta :

Answer:

0.93g

Explanation:

Given parameters:

Molecular weight  = 97.99g/mol

Number of moles  = 0.00948 mol

Unknown:

Mass of phosphoric acid = ?

Solution:

To find the mass of phosphoric acid, use the expression below;

      Mass of phosphoric acid = molecular weight x number of moles

   

Input the parameters and solve;

         Mass  = 97.99 x  0.00948

         Mass  = 0.93g

A mole is one of the convenient unit for making measurements in chemistry. It related to mass, volume, atoms, electrons e.t.c in many different ways.

Answer:

0.929g
