How much sodium is in 250 milliliters of normal saline?

Normal saline is 0.9% weight/volume sodium chloride to water. This is 9 grams per litre. NaCl has a molecular weight of 58.5, sodium (Na) has a weight of 23, which is 39.3% of the molecular weight. So sodium is 39.3% of the weight. 1 litre of saline has 9 grams, 250ml is a quarter of a litre, so has 9/4 grams = 2.25 grams. 39.3% of 2.25 g is 0.884 grams of sodium.


What is the molecular weight of fenol?

Phenol. C6H5OH 6 carbon atoms = 72.06 grams 6 hydrogen atoms = 6.048 grams 1 oxygen atom = 16.0 grams ===========================add = 94.108 grams per mole ---------------------------------


How many grams will it take you to get a liter?

The weight in grams of a liter of a substance will vary depending on the density of the substance. To convert between volume (liters) and weight (grams), you need to know the density of the substance in question. The formula to calculate this is: mass (in grams) = volume (in liters) x density (in grams per liter).


What is the molar mass of a substance?

The molecular weight (or, more appropriately, the molar mass) is defined by # of grams per # of moles. MW = g / mol For example: if you have 4 grams of substance and you know the substance to be 2 moles (say, for example, the balanced chemical equation), then your MW would be 2.


How many gram are in 1 ml of the Cinnamon essential oil?

The weight is equal to density multiplied by volume, so to find the weight in grams for Cinnamon oil we would have to know the density which is essentailly the weight per unit volume. Weight = Volume * Density Hope it helps --- Shailesh

How do you convert molecular weight from Dalton to grams?

To convert molecular weight from daltons to grams, you use the molar mass constant, which is 1 g/mol = 1 dalton. Therefore, the molecular weight in daltons is equivalent to the molar mass in grams per mole. Simply express the molecular weight in grams per mole.


What is the molecular weight of a compound in daltons and how does it convert to grams per mole (g/mol)?

The molecular weight of a compound is measured in daltons, which is a unit of mass used for atoms and molecules. To convert daltons to grams per mole (g/mol), you can use the conversion factor 1 dalton 1 g/mol. This means that the molecular weight in daltons is equal to the molecular weight in grams per mole.


What is the molecular weight of a compound in daltons and how can it be converted to grams per mole (g/mol)?

The molecular weight of a compound is the sum of the atomic weights of all the atoms in the molecule, measured in daltons. To convert this to grams per mole (g/mol), you can use the conversion factor 1 dalton 1 g/mol. This means that the molecular weight in daltons is equal to the molecular weight in grams per mole.


What is the difference between molecular weight in amu and molecular weight in grams?

The only difference is the name of the unit; the numerical values are the same. However, the value in amu is the mass of a single molecule, while the molecular weight in grams is the mass of Avogadro's number of molecules. The mass of Avogadro's number of molecules is called a Gram-mole. The molecular weight of , say, Hydrogen H2 is 2 amu. A gram mole of this would be 2 grams. The molecular weight in grams is the weight of this molecule in real grams and is an extremely small value.


How many grams of NaCl molecular weight 58.5 g mole -1 would you dissolve in water to make a 0.5M NaCl solution with 500 ml final volume?

You would need to dissolve 14.62 grams of NaCl in water to make a 0.5M NaCl solution with a final volume of 500 ml. This calculation is based on the formula: moles = Molarity x Volume (in liters), and then converting moles to grams using the molecular weight of NaCl.


How do you get gram molecular weight?

gram molecular weight = weight of one mole of the substance in grams for example 1 mole of water weighs 1 + 1 + 16 = 18 grams so gram molecularweight of water is 18g


Molecular weight of iron?

The molecular weight of iron (Fe) is approximately 55.85 grams per mole.


How do you convert 20mM tris-Hcl to gm?

let we have to calculate wait of 20mM tris-HCL for a solution of 1liter,then formula for molarity is Molarity= weight (in grams)/molecular weight X volume in liter hence 20/1000=wait/121.14X1 wait = 20 X 121.14/1000 (cross multiplication) wait = 2.42gm


How many grams are needed to make 1L of a 2 molar solution of NaCl with a molecular weight of 58?

The molecular weight of NaCl is 58.44. So you would need to add 116.88 g of NaCl into 1 L of water. Molarity X Required volume X Molecular weight 2 M/L X 1 L X 58.44 =116.88 g/L


How many grams KMnO4 take in 0.1N KMnO4 solution?

(158 g = 1 mole) --- molar mass of potassium permanganate. You also need to specify the volume to be made. For 1 liter just add 15.8 g in a volumetric flask to make 1000 ml (1 liter) of solution.


A 1.22g sample of an unknown has a volume of 1.73cm3. What is the density?

They use a number called a mole. This many atoms of an element equals its atomic weight in the periodic table. Molecular weight is the sum of atomic weight. Silver has an atomic weight of 108 grams/mole and Chlorine is 35.4 grams/mole. This makes AgCl 108 + 35.4 = 143.4 grams/mole. The % Chlorine is the atomic weight of Chlorine divided by the molecular weight of AgCl. 1 mole of AgCl would contain 35.4 grams / 143.4 grams = 25% Chlorine by weight. 1.22 grams AgCl would contain (0.25)*(1.22) = 0.30 grams of Cl. To find the Chlorine in the unknown, divide the weight of Chlorine from the experiment by the initial weight of the unknown. 0.30 grams / 0.63 grams = 0.48 = 48% Cl by weight.


How much sodium is in 250 milliliters of normal saline?

Normal saline is 0.9% weight/volume sodium chloride to water. This is 9 grams per litre. NaCl has a molecular weight of 58.5, sodium (Na) has a weight of 23, which is 39.3% of the molecular weight. So sodium is 39.3% of the weight. 1 litre of saline has 9 grams, 250ml is a quarter of a litre, so has 9/4 grams = 2.25 grams. 39.3% of 2.25 g is 0.884 grams of sodium.
