An acid is a hydrogen containing substance with a PH between 1-7 and is capable of donating a proton (hydrogen ion)
A because I said so I know so
Answer:
a) 37.04% b) 37.04% c) 9.63%
Explanation:
The theoretical percent recovery (Tr), is the total percentage of each compound in the sample. Depending on the technique used to recovery the compounds, the percent recovery will be less than the theoretical, because no technique is 100% efficient.
So, to calculate the theoretical, it will be the mass of the compound divided by the mass of the sample multiplied by 100%.
a) Tr = (250 mg)/(675 mg) * 100%
Tr = 37.04%
b) Tr = (250 mg)/(675 mg) * 100%
Tr = 37.04%
c) Tr = (65 mg)/(675 mg) * 100%
Tr = 9.63%
Molas mass C6H12O6 = 180.15 g/mol
1 mole C6H12O6 -------------- 180.15 g
?? molesC6H12O6 ------------ 3.10x10⁻³ g
3.10x10⁻³ x 1 / 180.15 => 0.00001720 moles
1 mole ------------------------- 6.02x10²³ molecules
0.00001720 moles ---------- ??
0.00001720 x (6.02x10²³) / 1 => 1.035x10¹⁹ molecules
