Calculate how long the chain will be if all the molecules in 5 g of hydrogen are placed next to each one.

Calculate how long the chain will be if all the molecules in 5 g of hydrogen are placed next to each one. Consider that the diameter of one molecule is 2.3 * 10 to the power of 10 m.

Data: m (mass of taken hydrogen) = 5 g; d (diameter of one hydrogen molecule) = 2.3 * 10 ^ -10 m.

Constants: Na (Avogadro’s number) = 6.02 * 10 ^ 23 mol-1; M (molar mass of hydrogen) = 2 g / mol.

1) Determine the number of molecules in 5 g of hydrogen: N / Na = m / M, whence N = m * Na / M = 5 * 6.02 * 10 ^ 23/2 = 15.05 * 10 ^ 23 molecules.

2) Calculate the length of the resulting chain: L = N * d = 15.05 * 10 ^ 23 * 2.3 * 10 ^ -10 = 34.615 * 10 ^ 13 m = 34.615 * 10 ^ 10 km.

Answer: The length of the resulting chain of molecules will be 34.615 * 10 ^ 10 km.
