Licemer1 [7]3 years ago
8 0

Answer: 1.1739*10²⁴ molecules

Explanation:

Using Avogadro's constant,

1 mole of any substance = 6.02*10²³ molecule/atom or particles.

Therefore 1.95 mole of water contains;

1.95 * 6.024*10²³ molecules = 1.1739*10²⁴ molecules.

Water has a molar mass of 18.015 g/mol . This means that one mole of water molecules has a mass of 18.015 g . So, to sum this up, 6.022⋅1023 molecules<span> of water will amount to 1 mole of water, which in turn will have a mass of 18.015 g . 2.7144moles H2O ⋅</span>6.022<span>⋅1023molec.1mole H2O =1.635⋅1024molec.</span>

Order the various instruments used for measuring water in this experiment (balances, graduated cylinders, beaker and pipette) fr
lara [203]

Answer:

(Most accurate) pippete>graduated cylinder>beaker>balance (Least accurate)

Explanation:

  1. <em>Most accurate. A pipette prived the most accurate method for delivering a known volume of solution, for example, a 10mL transfer pipette has an accuracy of ±0.02mL</em>
  2. A graduated cylinder is specifically used to deliver a known volume, its typical accuracy is ±1%, this means that a 100ml graduated cylinder is accurate to ±1mL.
  3. A beaker is a multipurpose cylindrical glass mainly used to hold liquids. Even though they are graduated, these marks are an estimation, the beaker's accuracy is around 10%.
  4. Least accurate. A balance measures an object's mass, even though water's density is close to 1, a balance is not the ideal equipment to measure volume, its capacity usually goes between 100-200grams and can measure mass to the nearest ±0.01mg to ±1mg.

I hope you find this information useful and interesting! Good luck!

When a gas is cooled at constant pressure, what happens to its molecules and volume?
Dima020 [189]
Assuming it's a perfect gas, we have PV=nRT hence if T goes down, V goes down up. The volume will decrease.

Sulfur dioxide gas reacts with oxygen gas to form sulfur trioxide gas. express your answer as a chemical equation. identify all
Firlakuza [10]
Sulfur trioxide (SO3) is a chemical compound that is a significant pollutant in gaseous form as it is involved in the production of acid rain. 

Industrially, sulfur trioxide is an important precursor to sulfuric acid and is formed from the reaction between sulfur dioxide (SO2) and oxygen gas (O2) as shown in the chemical equation below.
