135 grams of sodium has ______ moles.<br><br> (Enter just the number for this one.)

just olya [345]

Answer : 135 grams of sodium has 5.869 moles.

Solution : Given,

Mass of sodium = 135 grams

Molar mass of sodium = 23 g/mole

Formula used :

$\text{Moles of sodium}=\frac{\text{Mass of sodium}}{\text{Molar mass of sodium}}$

Now put all the given values in this formula, we get

$\text{Moles of sodium}=\frac{135g}{23g/mole}=5.869moles$

Therefore, the moles of sodium present in 135 grams of sodium is, 5.869 moles.

Why do living things need carbon

soldier1979 [14.2K]

Animals use oxygen to convert this food into energy they can use, and to maintain a steady supply of carbon atoms that are necessary for building any animal cells. Respiration also returns carbon dioxide back to the atmosphere as a waste product, where plants can reabsorb it in the process of photosynthesis. hope I helped.
