Melamine should be the right answer, i hope this helps.
Answer:
Percent yield is 25%
Explanation:
Information given is
Actual yield is 25 g
But the yield should be 100 g
The percent yield is defined as the ratio of the actual yield and the predicted yield it means that out of the predicted yield what percentage of the actual yield is obtained
∴ Percent yield = (Actual yield ÷ Predicted yield) × 100
In case of the given problem the percent yield will be
(25÷100) × 100 = 25%
∴ Percent yield = 25%
Answer:
2.03 atm
Explanation:
Number of moles of He = 1g/4g/mol = 0.25 moles
Number of moles of F2 = 14.0g/38 g/mol = 0.37 moles
Number of moles of Ar=19.0g/40g/mol = 0.48 moles
Total number of moles = 0.25 + 0.37 + 0.48 = 1.1 moles
From;
PV=nRT
P= pressure of the gas mixture
V= volume of the gas mixture
n= total number of moles of the gas mixture
R= gas constant
T= temperature of the gas mixture
P= nRT/V
P= 1.1 × 0.082 × 293/13
P= 2.03 atm
