Answer:
To calculate the number of moles in 5.75 g of sodium, we need to use the formula:
Number of moles = Mass of the substance / Molar mass of the substance
The molar mass of sodium (Na) is given as 23 g/mol.
Now, we can substitute the values into the formula:
Number of moles = 5.75 g / 23 g/mol
Number of moles = 0.25 mol
Therefore, there are 0.25 moles of sodium in 5.75 g of the element.
Hope that helps!
