Gasoline has a density of about 0.65 g/ml. (a) how much does 31 l (approximately 8 gallons) weigh in kilograms?

NemiM [27]3 years ago

The weight is influenced by the density and the volume. In this case, you are given the density of gasoline(0.65g/ml) and the volume (31l or 8 gallons). Since the unit is different, that mean you need to convert it. It will be easier to convert liter into ml than gallon so we will use 31L as volume. The calculation would be:

mass=density * volume= 0.65g/ml * 31l * (1000ml/l) * (1kg/1000gram)= 20.15kg

Baker’s yeast catalyzes the decomposition of hydrogen peroxide (dihydrogen dioxide) into oxygen and water. Directions: Add 10 mL
andreev551 [17]

Answer:

The unbalanced chemical equation: H₂O₂ → H₂O + O₂.

The balanced chemical equation: H₂O₂ → H₂O + 1/2O₂.

Explanation:

  • Hydrogen peroxide is decomposed into oxygen and water, which is a slow reaction.
  • It is can be catalyzed by using yeast.

The unbalanced chemical equation: H₂O₂ → H₂O + O₂.

The balanced chemical equation: H₂O₂ → H₂O + 1/2O₂.

1.0 mol of H₂O₂ is decomposed to 1.0 mol of H₂O and 0.5 mol of O₂.

The density (mass/volume) of aluminum is 2.70 times. 103 kilograms per cubic meter (kg/m3). what is the mass of an aluminum cyli
wariber [46]

Mass of aluminum = (1.50 m^3)( 2.70 x 10^3 kg/m^3) = 4050 kg 

The intention of density is the assembly per volume of the substance. This is an intrinsic property consequently the size (or any external feature) does not change this effects.

<h3>What is Aluminum?</h3>
  • Aluminum is a silvery-white metal, the 13 elements in the regular table. One surprising fact regarding aluminum is that it's the most widespread metal on Earth, making up more than 8% of the Earth's core mass. It's also the third most standard chemical essence on our planet after oxygen and silicon.
  • The formed aluminum is in everyday use in mining, manufacturing, and trade in the United States; the formed aluminum is used with reasonable uniformity in Great Britain and typically by chemists in the United States.
  • Aluminum (Al), also spelled aluminum, chemical component, a weightless silvery-white metal of main Group 13 (IIIa, or boron group) of the periodic table. Aluminum is the most plentiful metallic component in Earth's crust and the numerous widely used nonferrous metal.
