d=9.47xx10^4" g"

Explanation:

Step 1. Determine the density of nitrogen dioxide
d=1.45 " g"/"cm"^3

Recall that 1" cm"^3=1 " mL", so
d=1.45 "g"/"cm"^3=1.45 ("g")/(" mL")

Step 2. Write the mass as a function of density and volume.
"m"="d"xx"V"=(1.45 " g"/"mL")xx(67.2 " L")

Step 3. Convert L to mL
"m"="d"xx"V"=(1.45 "g"/"mL")xx(67.2 " L")xx((1000" mL")/(1" L"))=97,400 "g"

Or,
d=9.47xx10^4" g"
