a. 0.61 mol nacl
b. 0.72 mol nacl
c. 1.2 mol nacl
d. 1.8 mol nacl

Answer : The correct option is, (B) 0.72 mole of NaCl

Solution : Given,

Mass of NaCl = 42 g

Molar mass of NaCl = 58.44 g/mole

Formula used :

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

Therefore, the number of moles of NaCl is, 0.72 moles

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
