The molar mass of nitrogen is 14.0067amu or just 14amu.
Can u give us a clear question please
I believe the answer is "ions" because the definition of that word is "an atom or molecule with a net electric charge due to the loss or gain of one or more electrons."
So what you do is you write out each element separately and how many of that element on either side of the arrow S-8|S-1
O-2|O-2
on one side theres 8 (S) and 2 (O) and 1(S) and 2(O) if you put a number in front to balance it you are multiplying it the elements number like
SO2 if I put a 2 in front now I will have 2(S) and 4(O)
Answer is 1,8,8
A chemist reacted 0. 2 moles sodium benzoate with 0. 25 moles of hydrochloric acid. if she generated 22 g benzoic acid, the percent yield is 90%.
Reactant + HCl ------ Product
0.2 mol 0.25 22g
mol
Number of moles of reactant = 0.2mol
Molar mass of product = 122.12g
Number of moles of product = given mass/ molar mass
= 22g/ 122.12 g
= 0.180mol
Percent yield = (number of moles of product/ number of moles of reactant) × 100
= (0.180/0.2) × 100
= 90%
Thus we concluded that the percent yield of the given solution is 90%.
