Calculate the mass in mg of the aspirin tablet that contains 5.0 grains of aspirin . Assume 1 pound contains 7000 grains.
Rzqust [24]

Answer:

323.99 mg

Explanation:

We need to find the mass of the aspirin tablet that contains 5.0 grains of aspirin.

1 pound = 7000 grains

1\ \text{grain}=\dfrac{1}{7000}\ \text{pounds}

5\ \text{grain}=\dfrac{1}{7000}\times 5\ \text{pounds}\\\\=\dfrac{1}{1400}\ \text{pounds}

We know that, 1 pound = 453.592 grams

Also, 1 pound = 453592 mg

\dfrac{1}{1400}\ \text{pounds}=\dfrac{1}{1400}\times 453592\ mg\\\\=323.99\ \text{mg}

Hence, 4 grains of aspirin contains 323.99 mg.

How is rain different from water vapor​
azamat

Explanation:

Rain is when water falls from clouds in droplets that are bigger than 0.5 mm. Droplets of water that are about 0.2mm to 0.45mm big are called drizzle. Rain is a kind of precipitation. Precipitation is any kind of water that falls from clouds in the sky, like rain, hail, sleet and snow.

Other hand, Water vapor, water vapour or aqueous vapor is the gaseous phase of water. It is one state of water within the hydrosphere. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Water vapor is transparent, like most constituents of the atmosphere.

Explain how acids and bases directly or indirectly affect the hydrogen ion concentration of a solution.
ehidna [41]

By taking hydrogen ions, certain bases directly lower the H+ than OH- concentration. Other bases break down to create hydroxide ions, which indirectly lowers the H+ concentration.

<h3>What is the difference between acid and base?</h3>

H+ ion concentration is raised by an acid. A base is a chemical that, in an aqueous solution, produces hydroxide (OH-) ions, gives electrons, and receives protons. A donor of protons is an acid. A proton can enter a base. When dissolved in water, an acidic chemical compound produces a solution that has more H+ ion activity than clean water. A base is an aqueous material that releases hydroxide (OH-) ions, receives protons, or contributes electrons. A donor of protons is an acid. A base is a proton acceptor.
