alchemy is pseudoscience combining chemistry,magic,and philosophy during the middle ages.

Chemistry is the science that deals with the structure,composition,and properties of matter and the transformations that this matter undergoes.

Hello!

An antacid tablet containing 0.50 g of NaHCO3 is dissolved in 250 mL of water. What is the molar concentration of NaHCO3 in the solution ?

We have the following data:

M (Molar Concentration or Molarity) = ? (in mol/L)

m (mass) = 0.50 g

V (volume) = 250 mL → 0.25 L

MM (Molar Mass of NaHCO3)

Na = 1*(23u) = 23 u

H = 1*(1u) = 1 u

C = 1*(12u) = 12 u

O = 3*(16u) = 48 u

-------------------------------

MM (Molar Mass of NaHCO3) = 23 + 1 + 12 + 48 = 84 g/mol

We apply the data found to the formula of molar Concentration or Molarity, let's see:    The Molar Concentration is approximately 0.024 mol/L
