The mass of 5.2 x 10^22 manganese atoms in grams would be 635.784 grams.
What is Avogadro's constant?
Avogadro's number tells us how many particles are in one mole (or mol) of a substance. <u>Electrons</u><u>, molecules, or atoms</u> could be among these particles. Avogadro's number has a value of approximately 6.022140857×10²³ mol⁻¹. Avogadro's number tells us how many particles are in one mole (or mol) of a substance. <u>Electrons, molecules, or atoms </u>could be among these particles. Avogadro's number has a value of approximately 6.022140857×10²³.
Computation of mass
Avogadro calculated that every material had 6.022 x 10^23 atoms per mole.
5.2 x 10^22 atoms of Mn would contain how many moles?
= 6.022 x 10^23 /1 x 5.2 x10^22
=11.58 moles
Mn mass equals 11.58 moles multiplied by 54.9
= 635.784 grams

Answer:
Aluminum atomic number= 13
electron configuration = 2, 8 , 3
Hope it helps...........
Answer:
the difference between k and l is that (k) is more soluble than (L) because the mass of 200 has lower grams than 100.

3. Brand name
Volume of 3M solution: x
Moles in 3M solution: 3x
C = n/V
1,8 = 3x/0,05dm³
0,09 = 3x
x = 0,03dm³
A student need 0,03dm³ 3M HCl and 0,02dm³ of water.
