Question

calculate the molarity of 10.6 gm of na2co3 present in 2lit of solution​

Answer 1

Answer:please mark as brainliest

Explanation:

Molarity can be found with this formula:

molarity=number of moles/volume (L)

We know the volume, which is

500mL = 0.5 L.

We still need to know the number of moles, though, but we can find that from its mass.

10.6 g of Na2CO3 is:

10.6g molar mass=10.6g/106 g/mol=0.1 mol

Now, we can just plug those values in to solve for molarity:

molarity=0.1 mol/0.5 L=0.2 M

Answer 2

Answer:

the molarity of 10.6 gmm is
