Ablock of wood has a volume of 55 cm3 and a mass of 550 g. what would be its density? answer in units of g/cm3.

given,

volume (V)=55cm3

mass(m)=550g

now density=m/v

=550/55

=10 g/ cm3

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
