Question

How to find weight of .1M sodium carbonate solution

Answer 1

Answer:

Sodium carbonate is an inorganic salt with the chemical formula Na2CO3. This compound, used in such industrial applications as glass production, as an electrolyte or as a component of toothpastes, also works as a cleaning agent. Prepare sodium carbonate solutions with a certain concentration, commonly expressed either as a mass percentage of the dissolved compound (for example, a 5 percent solution) or in molarity—the number of moles of such a substance per 1 L of the solution.

Answer 2

Answer:

first of all you need to count the atomic mass of

Na-23u

c-12u

o-16u

now

in 1 mole of sodium carbonate there are 2 atoms of Na,1 atom of C, and 3 atoms of O

now molecular mass=2(mass of Na)+mass of C+3(mass of O)

=2(23)+12+3(16)

=46+12+48

=106u
