What is the percent by mass of water in na2so4 • 10h2o? use mc003-1.jpg. 5.59% 11.26% 44.08% 55.92%

The answer is 55.92%

Answer : The correct option is, 55.92 %

Solution : Given,

Molar mass of = 322 g/mole

Molar mass of water = 18 g/mole

The mass of =

Now we have to calculate the percent by mass of water in

Formula used :

Therefore, the percent by mass of water in is, 55.92 %

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.  

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
