Answer:
0.9 moles of Hg contain 5.418×10²³ atoms
Explanation:
As we know, Avogadro's number (NA) is the amount of particles that are contained in 1 mol → 6.02×10²³
Let's make a rule of three for this:
6.02×10²³ atoms are contained in 1 mol of Hg
5.418×10²³ atoms would be contained in (5.418×10²³ . 1) / NA = 0.9 moles
Answer:
2 E16 Hz or 2 * 10^16 Hz
Explanation:
The formula to determine frequency is f = c / λ.
f = frequency
c = speed of light
λ = wavelength
f = 3E8 / 1.5E-8
f = 2E16
This makes sense because UV light exists roughly
between 8E14 Hz and 3E16 Hz ----- 2E16 Hz falls in that range
Answer:
SO SORRY IF THIS IS WRONG BUT I HOPE THIS HELPS
Explanation:
Primary fertilizers include substances derived from nitrogen, phosphorus, and potassium. Various raw materials are used to produce these compounds. ... The phosphorus component is made using sulfur, coal, and phosphate rock. The potassium source comes from potassium chloride, a primary component of potash.
