The mass percent of hydrogen in CH₄O is 12.5%.

<h3>What is the mass percent?</h3>

Mass percent is the mass of the element divided by the mass of the compound or solute.

  • Step 1: Calculate the mass of the compound.

mCH₄O = 1 mC + 4 mH + 1 mO = 1 (12.01 amu) + 4 (1.00 amu) + 1 (16.00 amu) = 32.01 amu

  • Step 2: Calculate the mass of hydrogen in the compound.

mH in mCH₄O = 4 mH = 4 (1.00 amu) = 4.00 amu

  • Step 3: Calculate the mass percent of hydrogen in the compound.

%H = (mH in mCH₄O / mCH₄O) × 100%

%H = 4.00 amu / 32.01 amu × 100% = 12.5%

The mass percent of hydrogen in CH₄O is 12.5%.

In your reactions, you diluted the provided stock concentration of ADH for your alcohol. Calculate the actual ADH concentration
Fittoniya [83]

Answer:

10^-3 M.

Explanation:

The chemical compound known as the ADH is a hormone with chemical formula of C46H65N15O12S2, and the

Molar mass of 1084.24 g mol^−1. The chemical compound that is ADH is very important in human body as it helps in regulation of blood and also the regulation of water in human body.

STEP ONE: Convert the value of mg/ml to g/l. That is;

35mg/ml = 35g/l.

STEP TWO: Determine the number of moles.

The number of moles = 35 /35000 = 10^-3 moles.

STEP THREE: Determine the concentration.

Number of moles = concentration × volume.

10^-3 = concentration × 1.

The concentration of ADH = 10^-3 M.

Air is made of nitrogen, carbon dioxide, and small amounts of other gases. What is the pressure of O₂, total is 1 atm if PN₂ = 5
Stolb23 [73]

Answer:

The pressure of O₂ is 0.8 atm.

Explanation:

The pressure exerted by a particular gas in a mixture is known as its partial pressure. So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:

PT = PA + PB

This relationship is due to the assumption that there are no attractive forces between the gases.

In this case:

PT=Pnitrogen + Pcarbon dioxide + Pother gases

Being:

  • Pnitrogen: 593.4 mmHg
  • Pcarbon dioxide: 3 mmHg
  • Pother gases: 7.1 mmHg

and replacing:

PT= 593.4 mmHg + 3 mmHg + 7.1 mmHg

you get:

PT= 603.5 mmHg

Being 760 mmHg= 1 atm, you get:

PT= 603.5 mmHg= 0.8 atm

<u><em>The pressure of O₂ is 0.8 atm.</em></u>
