What is the molarity of 2.3 grams of Sodium Chloride dissolved in 25 ml of water?
To find the molarity, first calculate the moles of Sodium Chloride using its molar mass. Assuming 58.44 g/mol for NaCl, 2.3 grams is 0.039 moles. Then, divide this by the volume of solution in liters (25 mL = 0.025 L) to get a molarity of 1.56 M.
25 moles of sulfur dioxide how many grams of oxygen does it contain?
25 moles of sulfur dioxide contain 600 grams of oxygen. Each mole of SO2 contains 2 moles of oxygen, and the molar mass of O is 16 g/mol. So, 25 moles x 2 moles = 50 moles of O, which is 50 moles x 16 g/mol = 800 g of O.
How many mole of atoms are contained in 25.0 g naoh?
To find the number of moles of NaOH in 25.0 g, you first need to determine the molar mass of NaOH (40.00 g/mol). Then, divide the given mass by the molar mass to get the number of moles: 25.0 g / 40.00 g/mol = 0.625 mol of NaOH.
How many nitrogen atoms are in 25 g of CONH22 or Urea?
There are approximately 3.01 moles of urea in 25 g of CONH2, so there are 3.01 moles of nitrogen atoms. Therefore, there are 3.01 moles * 2 nitrogen atoms/molecule = 6.02 moles of nitrogen atoms in 25 g of CONH2, or urea.
How many moles of hydrogen atoms are present in 25 grams of water?
For this you need the atomic (molecular) mass of H2O. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. H2O= 18.0 grams2.5 moles H2O × (18.0 grams) = 45.0 grams H2O
The number of moles in 25 grams of NaCl?
For this you need the atomic (molecular) mass of NaCl. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaCl=58 grams 25.0 grams NaCl / (58 grams) = .431* moles NaCl *approximation
How many moles are there in 25 grams of Sr?
Sr is 87.6g/mol, and 25/87.6 = 0.285 moles.
How many grams of oxygen will be required to produce 25 moles of sulfur dioxide how many grams of oxygen will be required to produce 25 moles of sulfur dioxide?
800 g oxygen are needed.

To find the molarity, first calculate the moles of Sodium Chloride using its molar mass. Assuming 58.44 g/mol for NaCl, 2.3 grams is 0.039 moles. Then, divide this by the volume of solution in liters (25 mL = 0.025 L) to get a molarity of 1.56 M.
How many formula units are in 3.6 grams of nacl?
Use stoichiometry. 3.5g-> moles 22.99+16+1.0079=39.99 Now 3.5/39.99 = .088 moles of NaOH Now you can use avagadros number 6.022x10^23 .088 moles -> formula units .088/6.022x10^23 You should end up with 1.46x10-25 formula units. Yeah, I know, Chem sucks huh?
What is the mass in grams of 25 mol of sodium hydroxide?
The molar mass of sodium hydroxide (NaOH) is approximately 40 grams/mol. To find the mass of 25 moles of NaOH, you would multiply the number of moles by the molar mass: 25 mol * 40 g/mol = 1000 grams. So, the mass of 25 moles of sodium hydroxide is 1000 grams.
How many grams of 5 moles of lead?
5 moles of lead is equal to 1 036 g.
25 moles of sulfur dioxide how many grams of oxygen does it contain?
25 moles of sulfur dioxide contain 600 grams of oxygen. Each mole of SO2 contains 2 moles of oxygen, and the molar mass of O is 16 g/mol. So, 25 moles x 2 moles = 50 moles of O, which is 50 moles x 16 g/mol = 800 g of O.
How many moles are in 25 grams of UF6?
To calculate the number of moles in 25 grams of UF6, first determine the molar mass of UF6 (uranium hexafluoride) by adding the atomic mass of uranium (238.03 g/mol) to six times the atomic mass of fluorine (19.00 g/mol). This gives a molar mass of 238.03 + (6 * 19.00) = 352.03 g/mol. Next, divide the given mass of 25 grams by the molar mass to find the number of moles: 25 g / 352.03 g/mol ≈ 0.071 moles. Therefore, there are approximately 0.071 moles in 25 grams of UF6.
If 5 grams of NaCl is dissolved in 200 mL of water what is the NaCl concentration?
The answer is 29,22 g NaCl.
How many moles of formic acid is there in 25 grams of acetic acid?
I think you meant " How many moles of acetic acid in 25 grams of acetic acid? " We will use the chemist formula for acetic acid, 25 grams C2H4O2 (1 mole C2H4O2/60.052 grams) = 0.42 mole acetic acid =================
