Question

Calculate the mass of 1 molecule of CS2?​

Answer 1

Answer:

For 1 mole of CS2 = 12+32*2=76gm

Explanation:

For 1 molecule it will be 76/A

Answer 2

Answer: 76.14g/mol

Explanation:

In matter, the set of entities that exist. Atoms, molecules and ions are defined as moles. One mole of matter consists of 6.022 × 1023 molecules. Just like taking default values ​​to calculate various things. 1 dozen = 12 items Similarly, we use moles to quantitatively calculate the size of the smallest unit. The number of atoms present in

isotope 12 C 12 g (0.012 kg) is the number of particles present in 1 mole of the substance. One of the most important facts to keep in mind is that moles of matter always contain the same number of entities, whatever the matter.

To find out the exact number, we calculated the mass of the carbon-12 atom using a mass spectrometer and found it to be 1.992648 × 10-3 g.

We know that 1 mole of carbon weighs 12 g, so the total number of atoms in it is equal to 6

0221367×1023.No. The number of units per mole plays an important role in chemical calculations. For this reason, it is called Avogadro's number (NA). From the above discussion, we can say that the number of atoms present in 1 mole of hydrogen is equal to 6.022 × 1023.

While it is perfectly fine to calculate the masses of atoms, molecules, and other chemical compounds, these masses are of limited use because you cannot weigh single particles. I'm here. For mass measurements to be useful, stoichiometry must be expressed at the macroscopic level. The bridge between the particulate level and the macroscopic level is molar mass, which is the mass in grams of a mole of matter. Molar mass units follow that definition. grams/mole. Mathematically, the formula for molar mass is

molar mass = mass/mole = g/mol
