If iron (Fe) has an atomic mass of 56 amu, oxygen (O) has an atomic mass of 16 amu, and hydrogen (H) has a mass of 1 amu, the atomic mass of Fe(OH)3 would be 107amu (option B).
<h3>What is atomic mass?</h3>
Atomic mass is the average mass of atoms of an element. The mass number of a compound can be calculated by summing the atomic masses of each element in the compound.
According to this question, the periodic table reveals that iron (Fe) has an atomic mass of 56 amu, oxygen (O) has an atomic mass of 16 amu, and hydrogen (H) has a mass of 1 amu.
The atomic mass of Fe(OH)3 can be calculated as follows:
= 56 + (16 + 1)3
= 56 + 51
= 107amu
Therefore, if iron (Fe) has an atomic mass of 56 amu, oxygen (O) has an atomic mass of 16 amu, and hydrogen (H) has a mass of 1 amu, the atomic mass of Fe(OH)3 would be 107amu.

The work done by the three students is 3,000 J.
The energy transferred in the process is 3,000 J.
<h3>What is work done?</h3>
- Work done is the product of force and distance moved by the object.
W = Fd
The work done by the three students is calculated as follows;
W = 300 x 10
W = 3,000 J
<h3>What is energy transfer?</h3>
- This is means by which energy is converted from one form to another.
The energy transferred in the process is determined by work energy theorem.
E = W
E = 3,000 J

Answer:
Explanation:
The only one that doesn't have a time unit that is squared is the one that is a label for speed or velocity. Acceleration has a label with the time unit squared, like m/s/s. Choice D is the only unit for speed/velocity.
Charge = 66 wats which you can determine by measuring the electrons and neutrons by dividing.
Answer:
This question is improper, The Formula for work is force times distance, it only provides you with force and time so you cannot calculate work without the distance, Maybe you've mistaken work for power, The formula is work divided by time, but ask your teacher to provide you with more information because this entire question is WRONG. If it didnt give you a distance there is a possibility that it's 0 which would be 35N*0m, get some clarification.
Explanation:
INCORRECT question
W=F*D
P=W/T
