LUCKY_DIMON [66]
In dilute solutions, the unit osmolarity is being used. It usually has units milliosmols per liter of solution or mOsmol/L. An osmole defines the number of moles of the solute that would have an effect on the osmotic pressure of the solution. Osmolarity is calculated by the product of the molarity and the number of particles in the solution which is 2 for potassium chloride. We calculate as follows:
Osmolarity = molarity (# of particles)250 mosmol/L ( 1 osmol / 1000 osmol) = x moles / .100 L (2)
x moles = 0.0125 mol KCl
mass KCl = 0.0125 mol KCl ( 39 + 35.5 g/mol) = 0.93125 g KCl

Choose all the answers that apply. What are examples of how science has influenced technology?
Fudgin [204]

Answer:

A and B

Explanation:

A: The discovery of x- rays is a scientific discovery that led to X-ray machines which is technology.

B: Finding out that massive amounts of energy can be released by splitting the nucleus of an atom was the discovery and it led to nuclear power plants.

Satellites helping scientists map the earth doesn't really have an example of science. It just says that Satellites help scientists, and satellites are technology.

Robotic machines are also technology. Robots assisting doctors in surgery is technology helping people not science influencing technology.

So A and B would be the answers.

Hope this helps :)
