A liquid contains 0.25 mg of a substance per milliliter. How many grams of the substance will 3.5 L contain?
1 answer:
Answer:
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.

Step-by-step explanation:
P is the in-center
⇒PA=PE=PD because they are in-radius of the in-circle
We know that, tangent segments drawn from a point outside the circle are always equal in length
⇒DK=EK=7.2
In right triangle PKE,
using Pythagoras' Theorem :
