How to calculate ions from grams
Web1) find the molar mass of MgCl2 = 95.211 2) calculate the no. of moles = mass/molar mass = 9.53/95.211= 0.100093476 3) multiply the no. of moles by the no. of ions, there are 3 ions So, 0.100093476 * 3 = 0.300280429 4) now, multiply this answer by the Avogadro's constant and you get 1.81 x 10^23 WebIf you assume that you removed 100% of the ions on the exchange complex of the soil, then you sum the cmol c for the ions removed from the soil. The answer is 16 cmol c Kg-1. 9. To determine the mass, you multiply the number of centimoles of charge by the mass per centimole of charge. Note the units here are centimoles not moles.

Web5.3 Salinity Patterns All of the salts and ions that dissolve in seawater contribute to its overall salinity.Salinity of seawater is usually expressed as the grams of salt per kilogram (1000 g) of seawater. On average, about 35 g of salt is present in each 1 kg of seawater, so we say that the average salinity of the ocean salinity is 35 parts per thousand (ppt). Webis 1 g/mL, so we have 1000 g of solution. ∴ [Cu²⁺] = 1.8 × 10⁻⁵ g/1 L = 1.8 × 10⁻⁵ g/10³ g. We want to know how many grams of Cu²⁺ in 10⁶ g of solution, so we multiply the …
