Problem: Suppose you have 2.0 mol of O2 gas.How many coulombs of positive charge are contained in this gas in the atomic nuclei?Express your answer using two significant figures.

Avogadro's number,

$A = 6.023 \times 10^{23} p a r t i c l e s$

An oxygen molecule has 8 protons in each of the two nuclei: Z = 16

Charge of a proton,

$q_{p} = 1.6 \times 10^{- 19} C$
