In 8 mg Magnesium is:
8(mg) / 24.31(mg/mmole) = 0.329 mmole Mg
(molar mass Mg being 24.31 mg/mmole)
In 0.329 mmole Mg is:
0.329(mmole) * 6.02*1023(atoms/mole)*10-3(mole/mmole) =
= 1.98*1020 atoms of Mg.
(Avogadro's Number being 6.02*1023)
You have to divide 10 by molecular mass.Then get the answer.So the answer is 0.625
0.8 tablespoons are present in 12gm.
depend on product to product can vary from 35% to 45%
The cascade effect of a GM tube means that, as electrons are knocked off of their atoms by ionizing radiation in the presence of high voltage, the electrons interact with other atoms, producing more and more electrons, with the end result that a large pulse is detected by the counter. This is also known as avalanche mode. In this mode, ionizing events are simply counted, with no differentiation between the relative energies of those events. The GM tube is quantitatively more sensitive, at the cost of qualitative discrimination of overall dose rate.
it is cuz relative density = density of substance/density of water at 4oC.ie. if density of substance is 300 gm cm-3and density of water is 1 gm cm-3therefore : = 300 gm cm-3 / 1 gm cm-3as gm cm-3 is on both side it gets cancelled nHENCE..................THRE IS NO UNIT FOR RELATIVE DENSITY
(4/32)* 2 * 6.022*[10^23]
Are you familiar with mole concept. Well according to it 1 mole of anysubstance contains 6.023e23. First calculate the molecular mass of glucose which is (6*12)+12+(6*16)=180=y gm(say). Now find the mass of the sample glucose say x gm. Calculate the number of moles of glucose present which is found out by x/y. If its exactly 1 mole then the number of carbon atoms present are 6.023e23. Else use unitary method to find out for other values. For your mentioned number of carbon atoms the 0.0021 moles of glucose present.
The atomic weight of magnesium is 24.31; therefore, the number of moles in 100 gm is 100/24.31 = 4.11, to the justified number of significant digits.
So CO2 is 44g/mol. 48/44 is 1.0909091 moles. This multiplied by avagadros number is 6.57x1023 molecules. As there is 1 carbon per molecule, this also equals the number of carbon atoms

At GM parts site ":Number not found" It's probably an aftermarket part number, but it's not a GM
GM 12 Bolt
0.8 tablespoons are present in 12gm.
2.3 X 1024 atoms / 6.022 X 1023 atoms/mole X 107.87 gm/mole of silver = 412 grams
