Answer:
Percent yield = 75%
Explanation:
Given data:
Actual yield of ammonia = 60 g
Theoretical yield of ammonia = 80 g
Percent yield = ?
Solution:
Percent yield is calculated dividing the actual yield by theoretical yield and multiply by 100.
Formula:
Percent yield = Actual yield / Theoretical yield × 100
Now we will put the values in formula.
Percent yield = 60 g/ 80 g × 100
Percent yield = 0.75 × 100
Percent yield = 75%
So if the reaction yield is 60 g and calculated yield ( theoretical yield) is 80 g then the percent yield would be 75%.
Relative humidity is the percentage of what it can hold. Humidity is the measure of the amount of water vapor it can hold.
hope this helps ^^
Protons-19 because protons are equal to the atomic number which is 19 , electrons-19 electrons are equal to number of protons, neutrons-20 because the mass number of potassium is 39 so subtract 39 from 19 (atomic number) which gives us 20
Given the molarity of the solution is
.
The volume of the solution is 10.9/1000 L
Number of moles of HCl = Molarity * volume of the solution in L
Number of moles of HCl =
*
Number of moles of HCl = 2.7 moles.
Therefore number of moles of HCl in 10.9 ml of the stomach acid is 2.7 moles
