A salt solution has a concentration of 200 g/L. How many grams of salt are contained in 500 mL of this solution?
noname [10]

Answer:

100g/500mL

Explanation:

1ml is .001 of 1 L

this means that per one ml, there is 200g*.001, or .2g/mL, or simply .2g.

now we multiply this by 500, for the 500ml we are calculating. 500*.2=100.

We can also skip these steps and take 200g*.5L, as 500mL is 1/2 liter. We get the same outcome, so the answer is 100g

Nataliya [291]

The given question is incomplete. The complete question is:

Question: A(n) ________ is best defined as one who considers the impacts on the whole ecosystem, both the living and non-living, when considering an action.

(a) biocentrist

(b) ecocentrist

(c) anthropocentrist

(d) ethnocentrist

(e) relativist

Answer:

(b) ecocentrist

Explanation:

The approaches used for conservation of biodiversity differ from each other. The ecocentrist is the one who considers conservation and protection of the whole ecosystem including both the biotic and abiotic components. According to this concept, the biotic components and abiotic components of an ecosystem are interrelated. And the life forms can not sustain if their natural environment is degraded. Therefore, the conversation should be focused to preserve the ecosystem as a whole unit, not only the life forms.

How can an astronaut weigh different amounts when in different locations
Usimov [2.4K]
So, there’s this thing called the force of gravity and on Earth, it is what keeps you on the ground. On Earth, gravity gives physical objects weight. But the moon’s gravity is much weaker. This means that you would weigh less on the moon because there’s less gravity and it’s harder to stay down. This is why astronauts can look like they are hopping and skipping on the moon’s surface. Compared to Earth, they feel weightless.
