Water is flowing in a pipe with a mass flow rate of 100.0 lb/h (m water h, o=18.016). what is the (i) molar flow rate of h20 (gmol/s) (ii) mass flow rate of o (mw=16.00) in this stream (8 0/s)? (iii) mass flow rate of h (mw=1.00) in this stream (g h/s)?

i) 0,7 molH20/s

ii)11,2 g O/s

iii)1,4 g H/s

Explanation:

i) To find the molar flow rate of water, we just convert the mass of water to moles of water using its molecular weight(g/mol) and changing to the proper units (lb to grames and hours to seconds):

ii) Now we just consider the oxygen in the water stream (for 1 mole of water there is 1 mole of oxygen):

iii)Just considering the hydrogen in the stream (for 1 mole of water there is 2 moles of hydrogen):

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
