Question

How many moles of NaCl are equivalent to 15.6g NaCl

Answer 1

Hey there!:

Molar mass NaCl = 58.44 g/mol

Number of moles:

n = mass of solute / molar mass

n = 15.6 / 58.44

n = 0.2669 moles of NaCl

hope this helps!

Answer 2

Explanation:

It is known that number of moles equal mass divided by molar mass of compound.

Mathematically,     Number of moles = $\frac{mass}{molar mass}$

Since, it is given that mass is 15.6 g and molar mass of NaCl is 58.44 g/mol.

Therefore, calculate the number of moles of NaCl as follows.

           Number of moles = $\frac{mass}{molar mass}$    

                                         = $\frac{15.6 g}{58.44 g/mol}$    

                                         = 0.266 mol

Thus, we can conclude that there are 0.266 moles of NaCl are equivalent to 15.6g NaCl.
