Final answer:
The volume of petrol in the can is 2500cm³. When converted to liters, it is 2.5 liters, given that the density of petrol is 0.8g/cm³ and the petrol weighs 2000g.
Step-by-step explanation:
To find the volume of petrol in the can we can use the formula for density which is density = mass/volume. Given the density of petrol is 0.8g/cm³, and the mass of the petrol is 2000g, we can rearrange the formula to solve for volume as follows:
Volume = Mass / Density
Volume = 2000g / 0.8g/cm³ = 2500cm³
Since 1 liter is equivalent to 1000cm³, the volume of the petrol in liters can be calculated by:
Volume in liters = Volume in cm³ / 1000
Volume in liters = 2500cm³ / 1000 = 2.5 liters
The density of petrol is given as 0.8g/cm³, which means that 1 cm³ of petrol weighs 0.8 grams. To find the volume of petrol in the can, we can use the formula:
Volume (in cm³) = Mass (in g) / Density (in g/cm³)
So, the volume of petrol in the can is 2000g / 0.8g/cm³ = 2500 cm³.
To convert this volume to litres, we can use the conversion factor:
1 litre = 1000 cm³
Therefore, the volume of petrol in the can is 2500 cm³ / 1000 = 2.5 litres.
