Formic acid, HCOOH, is what causes the sting of bee stings. What is the formula weight of formic acid?
b) 46 amu
c) 50 amu
d) 58 amu
Answer:
Formula weight, or molecular weight is the sum of the atomic weights of all the atoms that make up the molecule.
H = 1 g/mol
C = 12 g/mol
O = 16 g/mol
HCOOH = 1 + 12 + 16 + 16 + 1 = 46 g/mol
46
don't you know how to calculate MW?
Do it like the guy showed you above but if you are at home and you want a quick reference.
Always use www.chemfinder.com
Type in formic acid and it will give you molecular weight :-).
