Answer: There are
molecules present in 183.2 grams of
gas.
Explanation:
Given: Mass = 183.2 g
Number of moles is the mass of substance divided by its molar mass.
As molar mass of water is 18 g/mol. Therefore, moles of
are calculated as follows.

According to the mole concept, there are
molecules present in one mole of a substance.
Hence, molecules present in 10.17 moles are calculated as follows.

Thus, we can conclude that there are
molecules present in 183.2 grams of
gas.
The two correct options are Poison dart frog and Boa constrictor. Both these organisms are pure carnivores which are also known as pure meat eaters in the food web. Carnivores are organisms in the food chain that only meat-eaters and never take any type of vegetation in their diet.
Explanation:
- A Poison dart frog purely survives on meat (meat- eater).
- Long sticky tongues are used to catch their prey such as ants, flies, insects.
- Since they produce high toxin levels, it has very few predators in the wild.
- Boa constrictor is also an organism that eats only meat.
- While they are young they eat prey like rats, squirrels and mice.
- The type of attack used by a boa constrictor is an ambush attack type. It attacks its preys using the surprise factor.
Answer:
D) 15375kgm/s
Explanation:
weight of the boy 25kg +weight of the car 1000kg= 1025kg so momentum =mass × velocity. so it's SI unit is = kg×m/s = kg m/s.
