Answer:
molarity = moles of solution/liters of solution
molarity = 1 mole/2 liters
molarity = 0.5 M
molarity = 50 moles/200 kg
molarity = 0.25 M
Explanation:
Answer:
4 significant figures
Explanation:
Significant figures are the units/digits within a number that make the number more accurate and precise.
All digits (except for 0) are always significant. Therefore, all the digits in 43.55 are significant. Since there are 4 digits in the given number, there are 4 significant figures.
Answer:
The correct answer is :'The gravitational force between two objects is related mathematically to their mass and the distance between them'.
Explanation:
A scientific law is a statement which explains physical phenomena and has been tested multiple times through the correct scientific methods and experimentation. It will give same results and observations after each conduct.
A scientific law comes into picture after the acceptance of a theory which explains or exposes the reason behind any physical phenomena occurrence.
So the best example of scientific law:
The gravitational force between two objects is related mathematically to their mass and the distance between them.
