$\bold{\underline{ Given :- }}$

Atomic number of an element with 6 neutrons and a mass number of 10

$\bold{\underline{ Let's \:Begin}}$

$\sf{We\: know\: that, }$

Atomic number is the number of protons in the nucleus of an atom

$\sf{Whereas ,}$

Mass number is the sum of protons and neutrons in the nucleus of an atom.

$\sf{We\: have \:number \:of \:neutrons = 6 }$

$\sf{ Mass\: number = 10 }$

$\bold{\underline{Therefore}}$

$\sf{ Mass\: number = Protons + neutrons}$

$\sf{ 10 = Protons + 6 }$

$\sf{ Protons = 10 - 6}$

$\sf{ Protons = 4 }$

$\sf{ Thus, \: the \: number \: of \: protons \: is \:4}$

$\bold{\underline{ Therefore,\:we\:know\:that, }}$

$\sf{ No\: of\: protons = Atomic \:number }$

$\sf{ 4 = Atomic \:number }$

$\sf { Hence, \:atomic\: number\: of\: the\: element\: is\: 4}$

Iron (Fe) has three isotopes. Calculate the average atomic mass of the element Fe using the following data: Isotope atomic mass

Maksim231197 [3]

Answer:

Average atomic mass = 55.83 amu

Explanation:

The formula for the calculation of the average atomic mass is:

$Average\ atomic\ mass=(\frac {\%\ of\ the\ first\ isotope}{100}\times {Mass\ of\ the\ first\ isotope})+(\frac {\%\ of\ the\ second\ isotope}{100}\times {Mass\ of\ the\ second\ isotope})+(\frac {\%\ of\ the\ third\ isotope}{100}\times {Mass\ of\ the\ third\ isotope})$

Given that:

For first isotope, Fe-54:

% = 6 %

Mass = 53.94 amu

For second isotope, Fe-56:

% = 92 %

Mass = 55.93 amu

For third isotope, Fe-57:

% = 2 %

Mass = 56.94 amu

Thus,

$Average\ atomic\ mass=\frac{6}{100}\times {53.94}+\frac{92}{100}\times {55.93}+\frac{2}{100}\times {56.94}$

<u>Average atomic mass = 55.83 amu</u>

Suppose your bedroom is 21 ft long, 17 ft wide, and the distance from floor to ceiling is 7 ft, 6 in. You need to know the volum

umka21 [38]

Answer:

1. 75.82 m^3 (cubic meters)

2. 75820 L (Liters)

Explanation:

Given data

L = 21 FT

W = 17 ft

h = 7 ft 6 in

Calculation

Formula to calculate volume is:

V= L×W×h

put the values in formula

V = 21 ft × 17 ft × 7 ft 6 in

V = 2677.5 ft

Now we will convert Cubic ft to cubic meters, as we know that 1 cubic meter is equal to 35.3147 cubic feet

V (m^3) = 2677.5 ÷ 35.3147

V (m^3) = 75.82 m^3

Now we will calculate liters

as we know that 1 cubic meter is equal to 1000 liters

so multiply the ans. with 1000

L = 75.82 × 1000

L = 75820 l
