Answer:
0.800
Explanation:
The formula for calculating moles given the mass and a compound is:
n=mM
n = moles
m = mass in grams (g)
M = molar mass (g/mol)
The molar mass is the sum of all the atomic masses in the compound.
Na=22.99 g/mol
N=14.01 g/mol×3→ (there are 3 N atoms)
Add them up and you get 65.02 g/mol
n=mM
=52.0g65.02gmol
=0.799753921 moles
=0.800 moles → (rounded to three sig figs)
Therefore, there are 0.800 moles in 52.0g of NaN3.
I hope this made sense :)
