What is the osmolarity of a 0.1 mole sodium chloride solution?
One mole solution of sodium chloride makes 1000 millimole. So 0.1 mole solution of sodium chloride will have 100 millimole in the solution.
What is molecular mass of Magnesium in Magnesium Chloride?
The molecular mass of magnesium in magnesium chloride is 24.305 grams/mol.
How many moles of sodium are needed to make 3.6 moles of sodium chloride?
One mole of sodium chloride is composed of one mole of sodium atoms. Therefore, 3.6 moles of sodium chloride would require 3.6 moles of sodium.
What is the mole ratio of Zn and Cl?
The percentage of magnesium in magnesium chloride is 25,537 %.
How many grams of sodium chloride is obtained by the action of chlorine with 4 moles sodium?
A mole of an element or compound is 6.022 x 1023 (Avogadro's constant) molecules of that substance. This number is the number of molecules it takes for an amount of substance to have a mass in grams the same as its molecular mass: carbon has a molecular mass of 12, so 6.022 x 1023 (one mole) carbon atoms have a mass of 12 grams. The molecular mass of sodium is 23 (22.989) so one mole of sodium has a mass of 23 grams. Sodium chloride has a molecular mass of 58.44 so a mole of NaCl is 58.44 grams. One mole of sodium will make one mole of sodium chloride. Na + Cl => NaCl So four moles of sodium will make four moles of sodium chloride. 4Na + 4Cl => 4NaCl Four moles of NaCl has a mass of 4 x 58.44 = 233.76 grams.
Does 1 mole of sodium chloride and 1 mole of magnesium chloride has same number of ions?
No: Each "mole", more precisely called "formula mass", of sodium chloride contains two ions, as shown by its formula NaCl, but each formula mass of magnesium chloride has three ions as shown by its formula MgCl2. This is true because sodium cations have only one positive electric charge unit, magnesium cations have two electric charge units, and chloride ions have one negative electric charge unit each.
What is the osmolarity of a 0.1 mole sodium chloride solution?
One mole solution of sodium chloride makes 1000 millimole. So 0.1 mole solution of sodium chloride will have 100 millimole in the solution.
What is molecular mass of Magnesium in Magnesium Chloride?
The molecular mass of magnesium in magnesium chloride is 24.305 grams/mol.
When one mole of sodium chloride dissociates in water it produces what?
When one mole of sodium chloride dissociates in water, it produces two moles of ions: one mole of sodium ions (Na+) and one mole of chloride ions (Cl-). This is due to the sodium chloride molecule breaking apart into its constituent ions when dissolved in water.
How many moles of sodium are needed to make 3.6 moles of sodium chloride?
One mole of sodium chloride is composed of one mole of sodium atoms. Therefore, 3.6 moles of sodium chloride would require 3.6 moles of sodium.
When one mole of sodium chloride dissociates in water it produces?
When one mole of sodium chloride dissociates in water, it produces one mole of sodium ions (Na+) and one mole of chloride ions (Cl-). Each ion carries a single positive or negative charge respectively.
How do you calculate what mass of magnesium chloride is formed when 54.75g of HCl is reacted with sufficient magnesium?
By starting with a balanced equation. Mg + 2HCl -> MgCl2 + H2 when they say sufficient magnesium they imply that magnesium is in excess and HCl limits and drives the reaction, or that both are equal in molarity/mass 54.75 g HCl (1 mole HCl/36.458 g)(1 mole MgCl2/2 mole HCl)(95.21 g/1 mole MgCl2) = 71.49 grams magnesium chloride produced -----------------------------------------------------------
Contains the fewest sodium atoms is it 1 mol sodium oxide 45g of sodium floride 50g of sodium chloride and 1 mole sodium nitrate.?
1 mole of sodium oxide contains the fewest sodium atoms because it contains 1 mole of sodium atoms. Each of the other compounds (45g of sodium fluoride, 50g of sodium chloride, and 1 mole of sodium nitrate) contains more than 1 mole of sodium atoms.
How do you use Mole in a sentence?
"I added a mole of sodium chloride to the reaction mixture."
What is the mole ratio of Zn and Cl?
The percentage of magnesium in magnesium chloride is 25,537 %.
How many grams of sodium are needed to produce 5.3 moles of sodium chloride?
molecular formula for sodium chloride = NaClIf the mole (n) for NaCl = 5.3 moles, then the mole of sodium (Na) = 5.3 moles as well. 1 to 1 ratio mass = moles X molar mass m = 5.3 x 22.9 = 121.37 grams of sodium in 5.3 moles of sodium chloride
Name the salt produced when hydrochloric acid reacts with magnesium?
1 Mole of Magnesium (Mg) would react with 2 Moles of Hydrochloric acid (HCl), to produce 1 Mole of Magnesium Chloride (MgCl2) (Salt), and 1 Mole of Hydrogen gas (H2).
