The mass of 025 mole of sodium is 92 grams. True False

False<br /><br />To determine the mass of 0.25 mole of sodium, we need to use the molar mass of sodium. The molar mass of sodium (Na) is approximately 23 grams per mole.<br /><br />To find the mass of 0.25 mole of sodium:<br /><br />\[ \text{Mass} = \text{moles} \times \text{molar mass} \]<br /><br />\[ \text{Mass} = 0.25 \, \text{mole} \times 23 \, \text{g/mole} = 5.75 \, \text{grams} \]<br /><br />Therefore, the mass of 0.25 mole of sodium is 5.75 grams, not 92 grams.
