Answer:
To calculate the actual yield of iron in moles, we need to use the molar mass of iron (Fe) and the given mass of iron produced.
The molar mass of iron (Fe) is approximately 55.845 g/mol.
Given:
Amount of Fe2O3 = 0.288 mol
Mass of Fe produced = 18.1 g
To find the moles of Fe produced, we can use the molar mass of Fe:
moles of Fe = mass of Fe / molar mass of Fe
moles of Fe = 18.1 g / 55.845 g/mol
moles of Fe ≈ 0.324 mol
Therefore, the actual yield of iron in moles is approximately 0.324 mol.
Answer:
27
Step-by-step explanation:
Simple interest is given by
I = Prt where I is the interest, P is the principle, r is the rate and t is the time
I = 300 * .03 * 3
I =27
27 dollars is made in interest
Answer: $27
Step-by-step explanation:
First you need to find 3% of 300 in order to find the annual interest.
3% = 0.03
300 * 0.03 = 9
The annual interest is $9. Now you need to multiply that by 3 to find the interest in 3 years.
9 * 3 = 27
The interest for 3 years is $27.
