Aliquid contains 0.25 mg of a substance per milliliter. how many grams of the substance will 3.5 l contain?

3.5 of the liquid will contain 0.875g of the substance.

Step-by-step explanation:

The problem states that a liquid contains 0.25 mg of a substance per milliliter. And asks how many grams of the substance will 3.5 L contain.

First step: Conversion of 3.5L to ml

Each liter has 1000ml. So:

1L - 1,000mL

3.5L - xmL

x = 1,000*3.5

x = 3,500mL

Second step: How many miligrams are there in 3,500mL?

The problem states that each ml of the liquid contains 0.25mg of a substance. So

1ml - 0.25mg

3,500 mL - xmg

x = 3,500*0.25

x = 875mg

Final step: Conversion of 875mg to g.

Each g has 1000 mg. So

1g - 1000mg

xg - 875mg

1000x = 875

x = 0.875g

3.5 of the liquid will contain 0.875g of the substance.
