Question

A glouber salt na2so4.h20 calculate mass required which contains 180g of water of crystalization

Answer 1

Answer:

Hi there

• Mass of water of crystallization = 180 g

Therefore moles of h2o= 180/18 = 10 moles

USING STOICHIOMETRY

• 1 mole of h20 combines with 1 mole of na2so4
• Therefore 10 moles will combine with 10 moles of na2so4

Therefore moles of na2so4= 10 moles

Therefore mass of na2so4=10*(46+32+64)

=10*142

=1420gm

=1kg42gm

Thank you
