The empirical formula for 200 grams of an organic sample which contains carbon,hydrogen, and oxygen is C3H6O
Depending on what chemicals you use it slows the reaction
THE DISTANCE IN TM SHOULD BE EQUAL TO 162 KM
Answer:
- Volume = <u>2.0 liter</u> of 1.5 M solution of KOH
Explanation:
<u>1) Data:</u>
a) Solution: KOH
b) M = 1.5 M
c) n = 3.0 mol
d) V = ?
<u>2) Formula:</u>
Molarity is a unit of concentration, defined as number of moles of solute per liter of solution:
<u>3) Calculations:</u>
- Solve for n: M = n / V ⇒ V = n / M
- Substitute values: V = 3.0 mol / 1.5 M = 2.0 liter
You must use 2 significant figures in your answer: <u>2.0 liter.</u>
The answer to the question is C
