Answer:
0.15 L
Explanation:
You need to first find the volume of the container. You can do this by dividing the mass by the density. This will give you the mass in mL.
5.00 kg = 5,000 g
(5,000 g)/(1.00 g/mL) = 5,000 mL
5,000 mL = 5 L
Now, find the volume the seawater will take up.
(5,000 g)(1.03 g/mL) = 4854.4 mL
4854.4 mL = 4.85 L
Subtract the two volumes to find the volume that left unfilled.
5 L - 4.85 L = 0.15 L
About 0.92 kg of benzyl salicylate would be needed in order to manufacture 325 tubes of sunscreen.
A tube contains 4.0 oz of the sunscreen and each one 2.5% benzyl salicylate.
2.5% of 4.0 oz = 0.1 oz
Thus, each tube would need 0.1 oz of benzyl salicylate.
325 tubes of the sunscreen is needed and each one requires 0.1 oz of benzyl salicylate. Hence, total amount of benzyl salicylate needed would be:
325 x 0.1 oz = 32.5 oz
From conversion:
16 oz = 1 lb
Hence,
32.5 oz = 32.5/16
= 2.03 lb
Also:
2.205 lb = 1 kg
2.03 lb = 2.03/2.205
= 0.92 kg

Answer:
Organisms and humans depend on each other to get by. Environmental science is important because it enables you to understand how these relationships work.
For example, humans breathe out carbon dioxide, which plants need for photosynthesis. Plants, on the other hand, produce and release oxygen to the atmosphere, which humans need for respiration.
Animal droppings are sources of nutrients for plants and other microorganisms. Plants are sources of food for humans and animals. In short, organisms and humans depend on each other for survival.
