Answer:
0.082 M
Explanation:
First we calculate the moles of KOH added, by multiplying its volume and concentration:
- 0.22 M * 16 mL = 3.52 mmol KOH
Given that <em>one mole of acid reacts with one mole of base</em>, in the lactic acid sample there were 3.52 acid moles as well.
Finally we divide the acid moles by the volume, to calculate the concentration:
- 3.52 acid moles / 43 mL = 0.082 M
Answer:
option c is correct answer.
during alpha decay mass of daughter atom is 4 unit less than its parent atom and its atomic number is 2 unit less than its parent atom.
Therefore, option c is answer.
You will need to look up some conversions of gram to lbs
1 gram = 0.00220462262 pounds
1 mL = 0.000264172052 US gallons
and mL to gal
1.035 g / cm^3 x 0.0022 lbs / 1 gram x 1 mL / 0.000264 gal
