Answer: molar mass of H2O2 = 34 g/mol
mass of H2O2 = 68 grams
Explanation:
The decomposition reaction of Hydrogen peroxide (H2O2) is:
2 H2O2 → 2 H2O + O
According to the equation the numbers of moles of H2O2 is 2 moles.
The molar mass of H2O2 = ( 16×2) + (1x2)
32 + 2 = 34 g/mol
∵ atomic mass of oxygen is 16 and hydrogen is 1.
Now, mole=
putting values
2=
mass of H2O2 = 2 × 34 = 68 grams
Answer:
0.41
Explanation:
In this question we have to use the RATE formula that is shown in the excel spreadsheet
Given that,
For the first case
Present value = $1,315
Future value or Face value = $1,000
PMT = 1,000 × 10% = $1,000
NPER = 10 years
The formula is shown below:
= Rate(NPER,PMT,-PV,FV,type)
The present value come in negative
After solving this, the yield to maturity is 5.77%
For the second case
Present value = $1,199
Future value or Face value = $1,000
PMT = 1,000 × 10% = $1,000
NPER = 5 years
The formula is shown below:
= Rate(NPER,PMT,-PV,FV,type)
The present value come in negative
After solving this, the yield to maturity is 5.36%
So the difference is
= 5.77% - 5.36%
= 0.41%
