Ordered: 0.3 gm. Available: 300 mg/tablet. How many tablets should be given?
dimulka [17.4K]

Answer:

1 tablet

Explanation:

Assuming that gm stands for gram:

Put everything in one unit, 0.3 g = 300 mg.

And given that each tablet is 300 mg:

mass/amount = 300mg / 1 tablet

300mg / X amount = 300mg / 1 tablet

(300mg/300mg) tablet = X = 1 tablet

So it is 1 tablet you need.

maria [59]

In the question, we are told that there are;

  • A loaf containing 33 slices
  • A loaf containing 33 slices A package of cheese containing 15 slices

We also know that he is making a sandwich that has 2 pieces of both cheese and bread.

Hence;

Total number of bread and cheese = 33 + 15.

Each loaf should have two pieces of each bread and the cheeses make a total of four pieces.

Therefore he can make = 33 + 15/4 = 12 sandwiches.

3.0 L of oxygen gas is heated from 100k to 250k. What is the new volume after the temperature has been increased???
alexandr402 [8]

Answer:

7.5 L

Explanation:

Using Charles' law, which is V1/T1=V2/T2, we can plug in these numbers to find the answer.  The law states that volume is directly proportional to temperature. 3.0L/100K = x L / 250 K. Solve for x to get 7.5 L. Hope this helps.

write down the way you had to behave to illustrate the behavior of particles as a gas condenses to form a liquid
Rainbow [258]

Gases near together and vibrate in position however, don't circulate beyond each other. In a liquid, the particles are interested in every different but now not as a great deal as they may be in a strong.

The particles of a liquid are near together, constantly transferring, and may slide beyond one another. The Kinetic-molecular concept attempts to explain the behavior of fuel molecules based totally on the nature of gasoline. The principle is grounded on  simple assumptions

In gases the debris passes swiftly in all directions, regularly colliding with every different facet of the box. With a boom in temperature, the debris gains kinetic strength and passes more quickly. Gasoline is a state of matter that has no constant form and no fixed extent. Gases have a decreased density than other states of the count, together with solids and liquids. there may be a high-quality deal of empty area between debris, that have loads of kinetic energy and aren't especially drawn to one another.
