What is the molarity of 250cm3 sodium chloride solution containing 2 moles?
The molarity of a solution is calculated by dividing the number of moles of solute by the volume of the solution in liters. In this case, there are 2 moles of sodium chloride in 250 cm^3, which is equivalent to 0.25 L. Therefore, the molarity of the solution is 8 M (2 moles / 0.25 L).
How many moles are in 8 grams of NaCl?
To find the number of moles in 8 grams of NaCl, you need to know the molar mass of NaCl, which is 58.44 g/mol. Divide the given mass (8 grams) by the molar mass to get the number of moles. Therefore, 8 grams of NaCl is equal to 0.14 moles.
What is the mass of 4 moles of CO2?
Hydrogen gas is H2. 1 moles H2 has a molar mass of 2.0158. Thus, 4 moles H2 gas has a mass of2.0158 g/mole x 4 moles = 8.063 g
How many chloride ions are in sample of salt that contains 2 moles of MgCl2?
Two Chloride ions (2Cl-) ions are needed with their -1 charge on each one to cancel out the +2 charge of the single Magnesium ion (Mg2+). So Magnesium Chloride would have the chemical formula: MgCl2
When a sodium atom reacts with a chlorine atom to form a compound the electron configurations of the ions forming the compound are the same as those of noble gas atoms?
That is correct. A noble gas (or at least all the noble gas elements heavier than helium) has an electron configuration of 8 electrons in its outer shell, and the sodium and chlorine ions in sodium chloride also have 8 electrons in their outer shell, just like a noble gas atom.
How many grams is 8 moles of sodium chloride (NaCl)?
The mass is 467,52 g.
What is the mass of 8 moles of sodium?
The molar mass of sodium is 22.99 g/mol. Therefore, the mass of 8 moles of sodium would be 8 moles x 22.99 g/mol = 183.92 g.
What is the mass of 8 moles of sodium atoms?
The molar mass of sodium is 22.99 g/mol. To find the mass of 8 moles of sodium atoms, you would multiply the molar mass by the number of moles: 22.99 g/mol * 8 mol = 183.92 g. Therefore, the mass of 8 moles of sodium atoms is 183.92 grams.
What is the mass of 8 moles of sodium Na atoms?
The molar mass of sodium (Na) is 22.99 g/mol. Therefore, the mass of 8 moles of sodium atoms would be 8 moles x 22.99 g/mol = 183.92 grams.
What is the molarity of 250cm3 sodium chloride solution containing 2 moles?
The molarity of a solution is calculated by dividing the number of moles of solute by the volume of the solution in liters. In this case, there are 2 moles of sodium chloride in 250 cm^3, which is equivalent to 0.25 L. Therefore, the molarity of the solution is 8 M (2 moles / 0.25 L).
How many moles of NaOH are in 8 g of NaOH?
To find the number of moles of NaOH in 8 g, first calculate the molar mass of NaOH (sodium hydroxide) which is approximately 40 g/mol (sodium - 23 g/mol, oxygen - 16 g/mol, hydrogen - 1 g/mol). Then, divide the given mass (8 g) by the molar mass to get the number of moles. So, 8 g / 40 g/mol = 0.2 moles of NaOH.
How many formula units of sodium chloride are present in a unit cell of sodium chloride crystal?
8
How many moles of KCI would be dissolved in 4 liters of water to make a 2 Molar solution?
We need 8 moles potassium chloride.
What is the total number of moles present in a 52.0 gram sample of NaN3 gram formula mass equals 65.0 mole?
To calculate the total number of moles in the 52.0 gram sample of NaN3, divide the given mass by the molar mass of NaN3. First, determine the molar mass of NaN3 by summing the atomic masses of its elements (sodium, nitrogen, and three times the atomic mass of nitrogen). Then, divide the mass of the sample by the molar mass of NaN3 to find the number of moles.
How many atoms will 8 grams of sodium contain?
8gNa*(1mol/22.989770)(6.022E23) = 2.09554E23 22.98 is the molar mass of sodium 6.022E23 is avgdros number, which pertains to the amount of molecules in a mole of substance.
