hey!!!
here is your answer
The answer is 0.017110756386119. We assume you are converting between moles NaCl and gram. This compound is also known as Sodium Chloride. 1 mole is equal to 1 molesNaCl, or 58.44277 grams.

hope it helps u....

Given,

10 grams of NaCl

To find,

The number of moles equivalent to 10 grams of NaCl.

Solution,

We can simply solve this numerical problem by using the following process:

As per stoichiometry;

1 mole of any element contains Avogadro's number of atoms, that is, 6.022 x 10^23 atoms.

And, the molar mass of any element is equal to the atomic mass of the same element.

{Statement-1}

Now, the molar mass of NaCl

= atomic mass of sodium + atomic mass of chlorine

= 23 grams + 35.5 grams

= 58.5 grams

Now, according to statement-1;

58.5 grams of NaCl is equivalent to 1 mole of NaCl

=> 1 gram of NaCl is equivalent to 1/58.5 moles of NaCl

=> 10 grams of NaCl is equivalent to 1/58.5×10 moles, which is equal to 0.17 moles of NaCl

Hence, 10 grams of NaCl is equivalent to 1/58.5×10 moles, which is equal to 0.17 moles of NaCl.
