Question

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

Answer 1

Answer: The mass of carbon dioxide is 6.65 g

Step-by-step explanation:

To calculate the mass of substance, we use the equation:

`\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}`

Volume of carbon dioxide = 3.5 L = 3500 mL (Conversion factor: 1 L = 1000 mL)

Density of carbon dioxide = 0.0019 g/mL

Putting values in above equation, we get:

`0.0019g/mL=\frac{\text{Mass of carbon dioxide}}{3500mL}\\\\\text{Mass of carbon dioxide}=6.65g`

Hence, the mass of carbon dioxide is 6.65 g

Answer 2

density is defined as mass per unit volume.

`density = (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
