Inside Hydrogen Atom
Chemical name: Magnesium Sulfate heptahydrate.. Need help!?
I have Mass of 8.81g of sample…. I need to know the number of moles of sodium Hydrogen carbonate in sample, number of formula units of sodium Hydrogen carbonate, number of atoms of sodium present, number of atoms of Hydrogen present, number of atoms of carbon present, number of atoms of oxygen present.
Also, I got 8.55g of the sample of magnesium sulfate heptahydrate inside the container… What is the number of moles, number of formula units magnesium sulfate heptahydrate, number of molecules of water, number of atoms of magnesium, number of atoms of sulfur, number of atoms of oxygen and number of hydrogen in the sample.
Thanks for the help!!!!!!!!!!!!
Tinnaya..
moles MgSO4*7H2O = 8.55 / 246.47 g/mol=0.0347
Moles H2O = 0.0347 x 7=0.243
molecules H2O = 0.243 x 6.02 x 10^23 = 1.46 x 10^23
atoms Mg = atoms S = 0.0347 x 6.02 x 10^23 02.09 x 10^22
atoms O = 8 x 6.02 x 10^23 x 0.0347=1.67 x 10^23
atoms H = 14 x 6.02 x 10^23 x 0.0347 =2.92 x 10^23
