Question:
If the molar concentration of sodium carbonate {eq}\rm (Na_2CO_3) {/eq} is {eq}\rm 2.5\ mM {/eq} (millimolar), what is the mass concentration of {eq}\rm Na_2CO_3 {/eq} (in {eq}\rm mg/L {/eq})? For the same molar concentration, what is the mass concentration of {eq}\rm Na^+ {/eq}?
What is a Mole?:
The mole is a unit. It is composed of {eq}6.02\times 10^{23} {/eq} particles. This number is known as Avogadro's number. The mole allows conversion from atomic mass units (amu) to grams of substance because 1 amu is the inverse of this number, {eq}1.66\times 10^{-24} g {/eq}
