    Let me give you an example.

    1 apple has a mass of 50 g
    2 apples will have a mass of 100 g
    3 apples will have a mass of 150 g
    4 apples will have a mass of 200 g
    5 apples will have a mass of 250 g

    100 apples? They will have a mass of 100 x 10 = 1000 g

    2000 apples? They will have a mass of 2000 x 10 = 20 000 g

    Can you try out with your problem now?
