Answer:

2×10² cg

Explanation:

We'll begin by converting each of the above to the same unit of measurement.

In this case, we shall convert each of the above to kg. This can be obtained as follow:

Conversion of cg to kg

1 cg = 1×10¯⁵ Kg

Therefore,

2×10² cg = 2×10² × 1×10¯⁵

2×10² cg = 0.002 kg

Conversion of dg to Kg

1 dg = 1×10¯⁴ kg

Therefore,

10 dg = 10 × 1×10¯⁴

10 dg = 0.001 kg

Conversion of mg to kg.

1 mg = 1×10¯⁶ Kg

Therefore,

2×10² mg = 2×10² × 1×10¯⁶

2×10² mg = 0.0002 kg

Conversion of ng to kg

1 ng = 1×10¯¹² kg

Therefore,

1×10⁵ ng = 1×10⁵ × 1×10¯¹²

1×10⁵ ng = 0.0000001 Kg

Summary

1. 2×10² cg = 0.002 kg

2. 10 dg = 0.001 kg

3. 2×10² mg = 0.0002 kg

4. 0.001 kg

5. 1×10⁵ ng = 0.0000001 Kg

From the above calculation, 2×10² cg is the highest mass.

The mass of a proton is 1.673 × 10-24 g. The mass of a neutron is 1.675 × 10-24 g. The mass of the nucleus of an 56Fe atom is 9.
Leokris [45]

Answer:

1.31 X 10^ -10 joules per Fe 56 atom

Explanation:

The mass of a proton is 1.673 × 10-24 g. The mass of a neutron is 1.675 × 10-24 g. The mass of the nucleus of an 56Fe atom is 9.289 × 10-23 g. What is the nuclear binding energy (in J) for 56Fe? (c = 3.00 × 108 m/s)

some of the theoretical mass will be converted to binding energy

by Einstein's famous relativity equation

E = mc^2

where E is in joules, m is in Kgm. c is in m/sec

56Fe is element 26 so it has 26 protons and  56 -26 =30 neutrons

its theoretical nuclear mass is

(26 X 1.673 X 10^-24) + (30X1.675 X 10^-24)  =

(43.498 X 10^-24) + (50.250 X 10^-24)=

93.748 X 10^24 gm

but its actual mass is 9.289 X 10^-23 g or

92.289 X 10^-24 g

the mas defect is the theoretical mass minus the actual

1.459 X 10^-24 gm =^

1.459 X 10^-27 Kgm

c = 3.00 X 10* m/s=

so joules of binding energy = (1.459 X 10^-27) X 9 X10^16)

1.31 X 10^ -10 joules per Fe 56 atom
