Number of molecules in 16 grams of h2co3

For this one u can work out the amount of moles in h2co3 by using moles=mass/mr(of h2co3 is 52)

so 16/62=0.258moles then u use the equation

number of particle = moles × 6.02×10^23

=0.258×6.02 ×10^23

=1.55×10^23 molecules.

hope this helps

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
