Answer:
0.0073 g
Explanation:
Considering:
Or,
Given :
For HCl :
Molarity = 0.010 M
Volume = 25 mL
The conversion of mL to L is shown below:
1 mL = 10⁻³ L
Thus, volume = 25×10⁻³ L
Thus, moles of HCl :
Moles of HCl = 0.00025 moles
Considering the reaction shown below as:-

2 moles of HCl reacts with 1 mole of 
So,
1 moles of HCl reacts with 1/2 mole of 
Also,
0.00025 moles of HCl reacts with
mole of 
Mole of
= 0.000125 moles
Molar mass of
= 58.3197 g/mol
Mass = Moles*Molar mass =
= 0.0073 g
Well, figures for efficiency vary a lot, but according to Bicycling Science it’s lubrication that matters most – lubing a dry chain can add 5% to the efficiency.
More interestingly (and I hadn’t read this bit in the book before) it varys a lot depending on gear ratio – bottom gear (22-28) is 99% efficient, top gear (42-11) is 88%. That’s a big difference
The sugar reacts with the gas, turning it to a semi-solid and sticky substance; clogging the gas lines along with many other things.
