For example, 2 moles of hydrogen gas combine with 1 mole of oxygen gas to produce 2 moles of water, by the chemical reaction: 2H2 + O2 = 2H2O. Molar Mass Calculator Common Compounds Periodic Elements Chemical Formula HCl also known as Hydrochloric Acid Molar Mass of HCl: 36.46 g/...
To go from molarity to pH, use your calculator or a similar tool to take the logarithm to the base 10 (the default base) of the molarity, reverse the sign to get a positive value, and you're done! Example: If the molarity of an aqueous solution is 6.3 × 10-5 M, what is the ...
