Ml of water to moles
WebDivide 1 gram of water by 18 grams per mole of water molecules and you get .0556 moles of water molecules in one cubic centimeter (one milliliter) of water. Each molecule has 3 atoms, so multiply .0556 by three to give you .1667 moles of atoms per cubic centimeter of water. Thank Writer. Blurt. WebThe calculator uses the formula M 1 V 1 = M 2 V 2 where "1" represents the concentrated conditions (i.e., stock solution molarity and volume) and "2" represents the diluted …

WebWhat is the molality of a solution containing 0.75 moles of sodium hydroxide in 500 milliliters of water at 25°C? The density of water at 25°C is 1.0 gram per milliliter. 3. If 149.1 g of KCI is dissolved in water to make 500 mL … Webcarbon dioxide (this question was asked twice) (A)Calculate the mass percent of a solution that is prepared by adding 40.2 g of NaOH to 416 g of H2O. Express your answer numerically. (B)Calculate the mass percent of a NaCl solution in which 147 g of NaCl is dissolved in 4.69 L of water at 25 ∘C (density = 0.997 g/mL).
WebMolecular weight of Water Water molecular weight Molar mass of H2O = 18.01528 g/mol Convert grams Water to moles or moles Water to grams Molecular weight calculation: … WebAt 15 degress the vapor pressure of water is 12.8 mm Hg. So that does agree with your intuition. At 15 degrees, the vapor only creates a pressure of 12.8 mmg Hg while at 25 degrees, the vapor creates a pressure of 23.8 mm Hg. Meaning, at 25 degrees, more water vaporizes to create a greater pressure. Comment.
WebAnswer (1 of 3): There are no moles in water, because presumably your water is pure. But a mole is probably pretty easy to fit into 1500 ml of water, since they’re pretty small. Ah, you probably meant to ask, “how many moles of water molecules are in 1500... There are no moles in water, because presumably your water is pure. Web(1) Calculate moles of a 15ml NaCl solution with concentration 0.2g/L The molar mass of NaCl is 58.44276 g/mol (Click here for molar mass calculator). So: mole = 0.2 * (15 / 1000) / 58.44276 = 0.000051332278 (mol) (2) What's the mass of NaCl required to make a 0.2mol/L solution in 15ml of water? The molar mass of NaCl is 58.44276 g/mol. So:
WebSince the molar mass (gram formula mass of sodium chloride is 58 grams per mole ( Na = 23 g and Cl = 35 g , 23 + 35 = 58 g/mol) the mole value of the NaCl is 0.5 moles (29 g / 58 g/mol = 0.5 moles). The mass of water is 1000 grams which is converted to 1.0 kg. Molality = moles of solute / kg of solvent. Molality = 0.5 moles / 1.0 kg = 0.5 molal
