<span>NO2 weighs 46.005 grams per mol. There are 6.02x10^23 molecules in a mol. In the given sample of 189.5 grams, there are 4.12 mols. This means that there are 2.48x10^24 molecules of NO2 in the given sample.</span>
Elements are like loners, compounds are like couples, and mixtures are like a group of friends that can also have couples (compounds)
The number of corresponding to each coefficient required to write the balanced equation for the reaction is as below
2 HNO3 + Mg(OH)2 = 2H2O + Mg(NO3)2
the coefficient is therefore
a=2
b=1
c=2
d=1
2 moles of HNO3 reacted with 1 mole of Mg(OH)2 to form 2 moles of H2O and 1 mole of Mg(NO3)2
