atomic mass of oxygen according to conventional scale is 16u. if we change the scale from 1/12 to 1/3 then its atomic mass will be

The new atomic mass of oxygen is 64u

Explanation:

Given

Taking the mass by part on the scale of 1/12 gives atomic mass of oxygen = 16 u

Now, when the scale is changed from 1/12 to 1/3, the new mass would become

The new atomic mass of oxygen is 64u

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
