0.129mol
Explanation:
-
Get the molar mass of
#NO_2# and convert 7.90g to moles by dividing with the said value.
#(7.90g)/(46.0055(g)/(mol))=0.17171859886mol# -
Divide by the mole coefficient
#4# and multiply by the coefficient#2# .
#(0.17171859886mol)/4*3=0.12878894914mol# -
Round off to significant figures.
#0.129mol#
