How many moles of h2o are equivalent to 97.3 grams of h20
g100num [7]

Answer : 5.405 moles of H_2O are equivalent to 97.3 grams of H_2O

Solution : Given,

Mass of H_2O = 97.3 g

Molar mass of H_2O = 18 g/mole

Formula used :

\text{ Number of moles}=\frac{\text{ Given mass}}{\text{ Molar mass}}

or,

\text{ Number of moles of }H_2O=\frac{\text{ Given mass of }H_2O}{\text{ Molar mass of }H_2O}

Now put all the given values in this formula, we get the moles of H_2O

\text{ Number of moles of }H_2O=\frac{97.3g}{18g/mole}=5.405moles

Therefore, 5.405 moles of H_2O are equivalent to 97.3 grams of H_2O

The atomic number of an element is 71. is this element diamagnetic or paramagnetic?
Mrrafil [7]
The  element  with atomic  number  71(lutetium) is  paramagnetic

  This  is  because  all  its   electrons   is  not  paired .  lutetium  has  electron  configuration  of  (Xe) 4f^14 5d^1 6S^2
Its 5d   sub shell  is  not  paired  since  the  d  sub shell  can  accommodate  a total  of  10   electrons  hence  lutetium  is  paramagnetic
