Taking into account the definition of density, the volume of digoxin should be 2.06 mL.

<h3>Definition of density</h3>

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space and allows us to measure the amount of mass in a certain volume of a substance.

So, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

density= mass÷ volume

You can observe that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

<h3>Volume of digoxin</h3>

In this case, you know that:

  • Density= 0.0250 mg/mL
  • Mass= 51.5 micrograms= 0.0515 mg (being 1 micrograms= 0.001 mg)

Replacing in the definition of density:

0.0250 mg/mL= 0.0515 mg÷ volume

Solving:

0.0525 mg= 0.0250 mg/mL ×volume

volume= 0.0515 mg÷ 0.0250 mg/mL

<u><em>volume= 2.06 mL</em></u>

In summary, the volume of digoxin should be 2.06 mL.

Answer:

D has to be based on facts so d would be the answer and idea that can only be proven true those are facts not hypothesis or guesses

Explanation:

based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world."

Two gas-filled tanks have the same volume, temperature, and pressure. They are identical in every way except that one is filled
Tems11 [23]

Answer:

The tank with O₂ weighs more.

Explanation:

We can find the mass of gas using the ideal gas equation.

P.V=n.R.T=\frac{m}{M} .R.T\\m=\frac{P.V.M}{R.T}

Considering the pressure (P), volume (V), temperature (T) and ideal gas constant (R) are the same, we can establish that:

m ∝ M

The mass is directly proportional to the molar mass. The molar mass of O₂ (32 g/mol) is higher than the molar mass of N₂ (28 g/mol). Therefore, the tank with O₂ weighs more.

If there is currently 50kg of U-235 present in Oklo, how much must have been present 750 million years ago when the reaction too
Viefleur [7K]
To answer this question, you need to know the concept of half-life, which is how a radioactive material decreases in mass over time.

The half life of U-235 is 703.8 million years. The first part of this problem is to find the scale factor. To do this, divide the time that has past by the half life, like this:

\frac{750}{703.8}  = 1.066
Now, take this scale factor and multiply it by the current mass, like this:

50 \times 1.066 = 53.3
This number is what you add to the current mass to get the original mass. That is because the scale factor showed us that it was just over one half life. Since after one half life, the mass is cut in half, and this is over one half life, when we add to the original it will be a little over double. This equation illustrates the final addition:

50 + 53.3 = 103.3
I hope this helped you. Fell free to ask any further questions.
