How many milliliters of 0.183 m hcl would be required to titrate 5.93 g koh?

Answers

Answer 1

Answer: Molar mass:
KOH = 56.0 g/mol

Number of moles of KOH :

5.93 / 36.5 => 0.1624 moles

KOH + HCl = KCl + H₂O

1 mole KOH --------------> 1 mole HCl
0.1624 moles KOH ----> ?

moles HCl = 0.1624 x 1 / 1

= 0.1624 moles of HCl

V ( HCl ) = moles / molarity

V(HCl) = 0.1624 / 0.183

V (HCl) = 0.887 L x 1000 = 887 mL

hope this helps!

Calculate the number of atoms of carbon in 3.8 moles of methane (CH4)

Answers

Total, 2.28916 × 10²⁴ atoms of carbon in 3.8 moles of methane.

To calculate the number of atoms of carbon in 3.8 moles of methane (CH₄), we need to consider the molecular formula of methane, which is CH₄. This indicates that each molecule of methane contains one carbon atom (C) and four hydrogen atoms (H).

First, let's find total number of carbon atoms in 3.8 moles of methane:

Number of moles of carbon in 1 mole of methane (CH₄) = 1 mole (because there is 1 carbon atom in each molecule of CH₄)

Number of moles of carbon in 3.8 moles of methane = 3.8 moles

Now, we'll use Avogadro's number to convert moles to the number of atoms:

Avogadro's number (NA) = 6.022 × 10²³ atoms/mol

Number of carbon atoms in 3.8 moles of methane = 3.8 moles × Avogadro's number

Number of carbon atoms in 3.8 moles of methane = 3.8 moles × 6.022 × 10²³ atoms/mol

Now, let's calculate:

Number of carbon atoms in 3.8 moles of methane ≈ 2.28916 × 10²⁴ atoms

So, there are approximately 2.28916 × 10²⁴ atoms of carbon in 3.8 moles of methane.

There are 6.02*10^23 molecules per mole substances. And there is one carbon atom per molecule of CH4. So the atoms number is 3.8*6.02*10^23=2.29*10^24.

Which of the following types of organelles are most important in providing a cell with energy

Answers

Mitochondria are the most important because they released the energy stored in food

I hope that's help you !

Final answer:

Mitochondria are the organelles that provide a cell with energy through ATP production via cellular respiration.

Explanation:

The organelles that are most important in providing a cell with energy are the mitochondria.

Within the mitochondria, ATP (adenosine triphosphate) is produced, which is the energy currency of the cell.

By undergoing cellular respiration, mitochondria produce ATP through oxidative phosphorylation, generating energy for various cellular processes.

Abdid is an astronomer who has been observing objects that orbit the Sun in the asteroid belt. He finds a previously undiscovered round, rocky object that is not similar in shape to the rest of the asteroids. What has Abdid most likely found?

Answers

Answer:

Abdid has most likely found a new dwarf planet.

Explanation:

Dwarf planets are too small to be considered planets, but are also two big to be considered something else. A dwarf planet has to have sufficient mass so that the self-gravity is strong enough to create its round shape. Other qualifications of a dwarf planet is that it has not cleared the neighborhood around its orbit and it cannot be a satellite. Based on the location, size, and shape of the object Abdid has discovered, it is likely he discovered a new dwarf planet in the asterioid belt. One of the most famous is Ceres.

since it is round and it is the asteroid belt it is most likely that he found a dwarf planet
