WebApr 2, 2024 · Thus, the molarity of pure water is 55.56 moles per litre. So, option C is the correct one. Note: We have to change the unit of density of water from gm/ml to Kg/L to calculate the molarity of pure water. This is because the molarity is calculated per litre of the solution and we have to make sure that the units are the same. WebOct 2, 2024 · To convert grams to moles, the molar mass of the solute is needed, which can be found on certain periodic tables . Molar mass of K = 39.1 g Molar mass of Mn = 54.9 g Molar mass of O = 16.0 g Molar mass of KMnO 4 = 39.1 g + 54.9 g + (16.0 g x 4) Molar mass of KMnO 4 = 158.0 g Use this number to convert grams to moles.

WebJan 31, 2024 · Find the molar mass of a water molecule (H₂O). It's ca. 18.015 g/mol. Convert the volume of the water to its mass, assuming that the density of pure water is 998 kg/m³: m = 6 l × 998 kg/m³ = 0.006 m³ × 998 kg/m³= 5.988 kg. It's easier to work with grams, so convert the mass: 5.988 kg = 5988 g. WebApr 9, 2015 · Just like there's a real molar concentration for water by itself ( 55.348 M ), there is a real molality for water by itself ( 55.510 m ). Let's say you had 1 L of water. At … WebHere, the volume of the solution is 26.8 mL. Calculate the molarity of the solution. Solution: The chemical formula of hydrochloric acid = HCl The chemical formula for Water = H2O The molecular weight of HCl = 35.5 ×1 + 1×1 = 36.5 moles/gram The molecular weight of H2O = 1 ×2 + 16 ×1 = 18 moles/gram the simon and garfunkel story facebook
