1.02 moles of NaCl are present in 60 grams sample of NaCl (sodium chloride).
How we calculate moles from grams?
Moles of any substance is calculated as:
n = W/M, where
W = given mass of NaCl = 60 grams (given)
M = molar mass of NaCl = 58.44 g/mole
On putting these values in the above equation, we get
n = 60 / 58.44 = 1.02 moles
Hence, 1.02 moles are present.
