How many milliliters of 0.142 M HCl would be required to titrate 4.44 g KOH?
4.44 g KOH x 1 mole KOH/56 g = 0.0793 moles KOH(x L)(0.142 mole/L) = 0.0793 molesx = 0.558 L = 558 mls neededHCl + KOH ==> KCl + H2O
How many atoms are in 3.50 moles of calcium?
There are 6.022 × 1023 atoms of potassium in every mole of potassium. Since one mole of KOH contains one mole of K, the answer is 6.022×1023 atoms of K. Therefore, 3.5 moles * 6.022E23 atoms/1 mole= 2.107E24
How many atoms in 4KOH?
1 fomula unit of KOH has 3 atoms: 1 potassium (K), 1 oxygen (O), and 1 hydrogen (H).
How many atoms are in 1 gram of KOH?
1 gram of KOH is equivalent to approximately (1.55 \times 10^{22}) atoms. This can be calculated by converting the mass of KOH to moles using its molar mass, and then using Avogadro's number (6.022 x 10^23) to determine the number of atoms in 1 mole of KOH (1 mole = 1 formula unit = 1 formula weight in grams).

Balance hi plus koh equals ki plus h2o?
The balanced chemical equation for the reaction between HI and KOH is: HI + KOH --> KI + H2O. In this reaction, hydrogen iodide (HI) reacts with potassium hydroxide (KOH) to form potassium iodide (KI) and water (H2O). The equation is balanced in terms of atoms and charge.

How many carats does a Koh-i-Noor diamond have?
The Koh-i-Noor diamond is 16 carat diamond ring originated from India. The name Koh-i-Noor is Persian it translates to "Mountain of Lights" in English.
How many moles are in 234.1 grams of KOH?
To find the number of moles in 234.1 grams of KOH, first calculate the molar mass of KOH (39.1 g/mol for K, 16.0 g/mol for O, and 1.0 g/mol for H). Add up the molar masses to get 56.1 g/mol for KOH. Divide the given mass (234.1 g) by the molar mass (56.1 g/mol) to find that there are approximately 4.17 moles of KOH in 234.1 grams.
How many moles of KOH are represented by 1.350g of KOH?
To calculate the number of moles of KOH, first find the molar mass of KOH which is 56.11 g/mol. Then, divide the given mass (1.350g) by the molar mass to get the number of moles. 1.350g / 56.11 g/mol = 0.024 moles of KOH.
