So yesterday my dad asked me "im ordered steak how do you want it?" and i said "on a plate" and he replied "no like how do you want it cooked" and i said "on a stove" my father sighed as i told him a story "oh that reminds me one time i went to a restraunt and i ordered a steak so rare no one could find it" (comment more jokes, also message me if you want more jokes)

good joke

Explanation:

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.  

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"
