Question

98.9 grams Na-
Convert to moles

Answer 1

To convert 98.9 grams of Na to moles, you divide the mass by the molar mass of sodium, which is 22.99 g/mol. This results in approximately 4.30 moles of sodium, which also equals 4.30 moles of ions, since sodium is a monatomic element with one ion per atom.

Step-by-step explanation:

To convert grams of sodium (Na) to moles, you will need to use the molar mass of sodium as a conversion factor. The molar mass of sodium (Na) is approximately 22.99 g/mol.

Step 1: Convert from grams to moles.

Use the molar mass of Na:

• 22.99 grams of Na = 1 mole of Na
• 98.9 grams of Na x (1 mole of Na / 22.99 grams of Na) = 4.30 moles of Na

Step 2: Determine the number of moles of ions present.

In sodium (Na), there is one ion per atom so the moles of ions would be the same as the moles of sodium.

• Result: 4.30 moles of ions

Note: Ensure that you are using the correct molar mass for the substance you are converting. The molar mass used here is for pure elemental sodium, not sodium in a compound like NaCl or NaOH.

Answer 2

4.31877 moles

Step-by-step explanation:

I believe its around 4.30 moles.

98.9g over 1 times 1 over 22.90 this is the molar mass of na= 4.31877 moles

Hope this helps!
