You take the grams of CO₂ times Avogadro's number divided by the molar mass.
c. table salt is a metalloid with properties of both reactants
Answer:
53.29% of acetic acid is Oxygen
Explanation:
Step 1: Given data
Acetic acid it's molecular formula is HC2H3O2. This means it consists of 3 elements Carbon, Hydrogen and oxygen.
Step 2: the molar masses
The molecular mass of acetic acid is:
4* H = 4* 1.01 g/mole
2* C = 2*12 g/mole
2*O = 2* 16 g/mole
Total molar mass = 4+ 24+32 = 60.052 g/mole
Step 3: Calculate the mass percent
32 g of the 60.052 g is Oxygen
(32/60.052) *100% = 53.29%
53.29% of acetic acid is Oxygen.
Answer:
Galeras has erupted more than 20 times since the 1500s. Volcanic activity has been frequent in the last five years, including an eruption in January 1993 that killed nine people on a scientific expedition to the volcano summit. Chuck Wood of VolcanoWorld was on Galeras at that time but was not injured
