Answer:For a typical experiment, you should plan to repeat it at least three times (more is better).
Explanation:
The answer is the 3. Hope this helped!
States of matter are determined by temperature. When the temperature is more cold, the particles move less. The colder the temperature, the more solid something becomes. Because the particles are in fixed positions, they do not move much, they are colder, and they are solid. Also, you cannot pass your hand through locked atoms. If you swipe your hand through water or gas, it parts. Solids, however, are fixed and cannot be passed by without significant force to break it.
Answer:
248.4 mL
Explanation:
Erlenmeyer = 78.649 g
Erlenmeyer + Water = 327.039 g
Water = (Erlenmeyer + Water) - Erlenmeyer
Water = 327.039 - 78.649
Water = 248.4 g
if the density of water is 1 g/mL, we can say that each mL of water weigh 1 g, so we have 248.4 mL of water in the Erlenmeyer Flask.
