Question

an organic compound contain 49.3% carbon, 6.84% hydrogen and its vapour density is 73. find the molecular formula of the compound

Answer 1

The uncertainity of a moving bullet of mass 10g is 10^-5 m. Calculate the uncertainity in its velocity?

According to uncertainty principle

Δx.Δmv = ℎ / 4π

Δv = ℎ 4πmΔ

x=6.626 × 10−34 / 4×3

=> ×14×10−2×10−5

=> 5.27×10−28 m/s ...
