Answer:
I would say B but i am not sure hope it helps
Explanation:
An object will be floating in water if the density is lower and will be sink if the density is higher. Water density would be 1000g/liter or 1g/ml. To determine whether the object float or sink you need to calculate both object density.
The density of object A would be: 2g/ 0.5liter= 4g/liter
The density of object B would be: 3g/ 5liter= 0.6g/liter
It is clear that the object is much lighter than water so both objects would float.
It’s the second answer. “it gets used for metabolic process & released as heat” i think.
229.25 mL of isopropyl alcohol
425.75 mL of water
Explanation:
Knowing that the solution have a 35.0 % (v/v) isopropyl alcohol in water, we can calculate the volume of each component as following.
volume of isopropyl alcohol = (35/100) × solution volume
volume of isopropyl alcohol = 0.35 × 655 mL = 229.25 mL
Now, knowing the volume of isopropyl alcohol we can determine the volume of water.
volume of the solution = volume of isopropyl alcohol + volume of water
volume of water = volume of the solution - volume of isopropyl alcohol
volume of water = 655 mL - 229.25 mL = 425.75 mL
