Answer:
<h2><u>Of moles of NH4NO3 = 16/80 i.e. 0.2 moles of Ammonium Nitrate. 1 molecule of NH4NO3 contains 1 atom of N. Hence, 1 mole of NH4NO3 would contain 1 mole of Nitrogen atoms and therefore 0.2 moles of NH4NO3 should contain 0.2 moles of Nitrogen atoms</u>.</h2>
Explanation:
The question is incomplete , the complete question is;
The mass of each Wt isotope is measured relative to C-12 and tabulated below. Use the mass of C-12 to convert each of the masses to amu and calculate the atomic mass of Wt.
Wt-296 = 24.6622
Answer:
The atomic mass of Wt-296 is 195.9464 amu.
Explanation:
1 amu is defined as 1 by twelfth of the carbon-12 mass.
Mass of an isotope Wt-296 = 24.6622
Mass of an isotope Wt-296 in amu = M
The atomic mass of Wt-296 is 195.9464 amu.
Answer:
The volume will goes to decrease.
Explanation:
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
when pressure is going to increase the volume will goes to decrease and vice versa.
Consider the initial volume is 10 L at initial pressure of 15 atm when pressure is increased to 30 atm the volume will be,
Now we will put the values in formula,
P₁V₁ = P₂V₂
15 atm × 10 L = 30 atm × V₂
V₂ = 150 atm. L/ 30 atm
V₂ = 5 L
This liquid is sometimes colored alcohol but can also be a metallic liquid called mercury. Both mercury and alcohol grow bigger when heated and smaller when cooled. Inside the glass tube of a thermometer, the liquid has no place to go but up when the temperature is hot and down when the temperature is cold. Mercury is very reactive and works best. But mercury is also very a radioactive element. So, if you break the thermometer, you could get in trouble (radio active posoning) Alcohol work well, it is not radioactive and can't kill you.
Okay, hope I helped
