#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"#
