What is the mass of 3.5 l of co2(g)? (density = 0.0019 g/ml, answer to hundredths place)?

monitta

Density is defined as mass per unit volume.
$density = \frac{mass}{volume}$
the mass of 1 mL of CO₂ is - 0.0019 g
3.5 L = 3500 mL
then the mass of 3500 mL of CO₂ is - 0.0019 g/mL x 3500 mL = 6.65 g
mass of 3.5 L of CO₂ is 6.65 g
