Gay-Lussac's law states that the pressure of a gas is directly proportional to the absolute temperature provided mass & volume of gas is constant. At constant volume, the pressure of the gas increases with increase in temperature and decreases with a decrease in temperature which is expressed as: PαT -------- (at constant volume & mass)

Posted by Priyanshi Kathayat 1 year, 1 month ago

CBSE > Class 11 > Chemistry

1 answers

Anjan Karthi 1 year, 1 month ago

No of moles = 2g /40g = 1/20 = 0.05 mol. // Volume given = 1 decilitre = 1/10th L. Therefore, molarity M = 0.05 / (1/10) = 0.05 × 10 = 0.5 mol/L.//

How to find atomic radii?

Posted by Vaishnavi B 1 year, 1 month ago

CBSE > Class 11 > Chemistry

1 answers

Anjan Karthi 1 year, 1 month ago

Well, varies. If you want to find for unbonded atoms, you may have to consider Vander Waal's radius. For covalently bonded atoms, it is covalent radius, for metallic lattices, it is metallic radius. All have the same formulae which is half the intermolecular distance but the difference comes in their ranges. Generally, Vander Waal's > Metallic > Covalent > Ionic radii.

ANSWER

A compound is found to contain 54.67% of carbon 9.1% of hydrogen and the remaining is oxygen. Vapour density of the compound is 22. Calculate its molecular formula

Posted by Sai Akshara 1 year, 1 month ago

CBSE > Class 11 > Chemistry

1 answers

Anjan Karthi 1 year, 1 month ago

No of moles of C = 54.67 (out of 100g) / 12 = 4.5 . No of moles of H = 9.1 / 1 = 9.1 . No of moles of O = (100 - 63.77) / 16 = 2.25 . Therefore, ratio of empirical formula = C:H:O = 2:4:1 . So, empirical formula = C2H4O (Mass = 24 + 4 + 16 = 44) So, N = M/EM = 2 × 22/44 = 1.// Therefore, molecular formula = C2H4O. //
