Given the equation 2na+cl2 →2nacl how many moles of nacl will be produced from 59.0 grams of na, assuming cl is available in excess?

2.56 moles

Explanation:

To calculate the moles :

Na is the limiting reagent as it limits the formation of product and chlorine is the excess reagent.

According to stoichiometry :

2 moles of Na produce = 2 moles of NaCl

Thus 2.56 moles of Na produce =  of NaCl

Thus 2.56 moles of NaCl are produced.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
