What is the mole fraction of sodium chloride in a solution containing 0.23 moles of NaCl and 5.5 moles of water?

0.040

hope this helps :)

Explanation:

NaCI=mol NaCI/mol NaCI+mol H2O

NaCI=0.23 mol/0.23 mol+5.5 mol

NaCI=0.23 mol/5.73 mol=0.040

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.
