A bag of potting soil has a mass of 5 kilograms. Selina uses 175 grams of the soil to pot a plant.

What is the mass of the potting soil left in the bag?

The mass of the potting soil left in the bag is 4,825 grams or 4.825 kilograms

Step-by-step explanation:

Information given to us to answer the question correctly:

Mass of the bag of potting soil = 5 kilograms

Mass of potting soil to pot a plant = 175 grams

Let's recall that 1 kilogram = 1,000 grams, therefore:

5 kilograms = 5,000 grams

Mass of the potting soil left in the bag = Mass of the bag of potting soil - Mass of potting soil to pot a plant

Replacing with the values we have:

Mass of the potting soil left in the bag = 5,000 - 175

Mass of the potting soil left in the bag = 4,825 grams

4,825 grams = 4.825 kilograms
