how many moles are in 174 g of NaCl??​

Sagot :

Solution:

Step 1: Calculate the molar mass of NaCl.

molar mass = (22.99 g/mol × 1) + (35.45 g/mol × 1)

molar mass = 58.44 g/mol

Step 2: Calculate the number of moles of NaCl.

[tex]\text{moles of NaCl = 174 g NaCl} × \frac{\text{1 mol NaCl}}{\text{58.44 g NaCl}}[/tex]

[tex]\boxed{\text{moles of NaCl = 2.98 mol}}[/tex]
