Answer:

Under #4*kg#.

Explanation:

Density, #rho# #=# #("mass")/("volume")#; thus #"mass" = rhoxx"volume"#

#6cancelL xx 1000*cancel(mL)*cancel(L^-1) xx 0.6*g*cancel(mL^-1)#

#=# #??g#

The volume was quoted at a certain temperature because volume varies with temperature. If the temperature had been #15# #""^@C#, would you expect volume to increase or decrease? Why?

Answer:

The mass will be 3600 g of gasoline.

Explanation:

Since density is in g/mL, convert 6 L to mL.

#6cancel"L"xx(1000"mL")/(1cancel"L")=6000"mL"#

To calculate the mass of 6000 mL of gasoline, multiply the volume times its mdensity.

#6000cancel"mL"xx(0.6"g")/(1cancel"mL")="3600 g gasoline"#
