Answer:
The unit of pressure in the SI system is the pascal (Pa), defined as a force of one Newton per square meter. The conversion between atm, Pa, and torr is as follows: 1 atm = 101325 Pa = 760 torr. A standardized prefix system indicates fractions and multiples of metric units (e.g. milli-, mega-).
Answer:
Pascals(Pa)

the area. The scientist wants to conduct a study that will measure the change in the
local mosquito population over a period of three months. Which research method
would give the scientist the best data for conducting his study?
A. a three-month case study observing the behavior of animals that depend on
mosquitoes for food
B. a survey asking residents about their observations of the local mosquito
population
C. a collection device in the area that counts the number of mosquitoes caught
weekly
D. a controlled lab experiment with mosquitoes that limits watercolor the
experimental group
Answer: (C.) a collection device in the area that counts the number of mosquitoes caught
weekly
Explanation: I took the test :D
The most suitable research method for measuring a change in the mosquito population due to construction would be 'a collection device in the area that counts the number of mosquitoes caught weekly'. This method provides quantifiable, reliable data over the three-month study period.
To thoroughly study the change in the local mosquito population due to the construction, the most suitable research method for the scientist would be to use 'a collection device in the area that counts the number of mosquitoes caught weekly' (option C). This method would provide direct, quantifiable data about the mosquito population, showing changes on a weekly basis over the three-month study period.
A case study (option A) would not provide direct data about the mosquito population. Instead, it would provide indirect observations through the behavior changes of animals that prey on mosquitoes. Similarly, a survey (option B) relies on residents' subjective observations, which may not be reliable or accurate. Finally, a controlled lab experiment (option D) does not account for the plethora of variables present in a natural environment, thus limiting its effectiveness in this situation.

Answer:
69.036 g of Compound is required to obtain 48.45 g of Oxygen.
Explanation:
Let us assume that the total mass of the compound is 100 g. So it means that this compound weighing 100 is composed 70.18 % of Oxygen or among 100 g of this compound 70.18 g is constituted by oxygen only. Hence, we can make a relation as that,
70.18 g O is present in = 100 g of a Compound
So,
48.45 g of O will be present in = X g of a Compound
Solving for X,
X = 100 g × 48.45 g ÷ 70.18 g
X = 69.036 g of Compound
