How many moles are in 10.5 g of sodium?
Explanation: The number of moles present in 10.5 grams of NaCl are, 0.179 moles. Therefore, the number of moles present in 10.5 grams of NaCl are, 0.179 moles.
How many moles are present in NaCl?
One mol of NaCl (6.02 x1023 formulas) has a mass of 58.44 g.
How many moles and grams are in NaCl?
We know that 1 mole of any substance contains the amount of mass equal to its molar mass. So, 1 mole of NaCl has a mass of 58.5 g.
What is the mass of 10 moles of NaCl?
Hence, the molar mass of NaCl is 58.5 g/mol.
How many grams of sodium are there in 10g of sodium sulfate?
Sodium sulfate (Na2SO4 N a 2 S O 4 ) has a molar mass of 142.04g/mol. Therefore, 10g of it represents 10 / 142.04 = 0.07mol.
How do you find moles of sodium ions?
First, calculate the moles of sodium sulfate you have in a 14.2g sample. Now, for every 1 mol of Na2 SO4 you have 2 moles of Na+ ions. Multiple the moles of Na2 SO4 that you found just then by 2 to obtain the moles of sodium ions. Use Avogadro’s number (6.022 x 1023 ) to find the number of ions present.
How many grams of NaCl are in 23.4 moles of NaCl?
The molecular weight of NaCl = (23 +35.5) = 58.5g/mol.
How many moles are there in 250g of NaCl?
0.125 mol; 7.32 g.
How many moles and grams of NaCl are present in 250cm3 of a 0.5 m NaCl solution?
Given, volume of solution is 250ml or 0.25 liter. So, number of mole of solute (NaCl) is 0.125mole present in solution . Hence, 7.3125 grams of sodium chloride is present in 250mL.
