According to Avogadro's law 1 mole contains 6.022 ×10^23 particles
1 mole of carbon = 44.01 g/ mol
Therefore;
44.01 g = 6.022 ×10^23 molecules
Hence, 1.68×10^26 molecules will have a mass of ;
(44.01 × 1.68×0^26) / 6.022×10^23
= 1.228 × 10^4 molecules
Answer:
meteorologist, barometers, anemometer, thermometer, balloon, satellites, station models, isotherms, isobars
Explanation:
253.15
The temperature T in degrees Celsius (°C) is equal to the temperature T in Kelvin (K) minus 273.15:
T(°C) = T(K) - 273.15
Chemical energy starts when you eat or drink something bc when you eat or drink something the energy of that food or drink goes into ur muscle.Mechanical occurs when you move ur muscle like when you kick a ball its mechanical.Thermal happens when ur hot or sweating
Answer:
I believe you are asking about the objective lens or eyepiece.
Explanation:
Objective lenses are used to magnify objects enough for you to see them in great detail
Eyepiece/Ocular is what you look through at the top of the microscope.
A tube connects the eyepiece lens to objective lenses, which enhance the magnification power of the eyepiece lens. Both the eyepiece and the objective lens contribute to the magnification of the object.
The eyepiece lens usually magnifies 10x, and a typical objective lens magnifies 40x.
