Answer:
2.3 x 10-23 g.
Explanation:
The mass of a single atom is the mass number, 14, is the mass in grams of one mole of carbon.
One mole of Nitrogen atom is 6.022 x 1023 atoms (Avogadro's number). This can then used to convert a nitogen atom to grams by the ratio:
mass of 1 atom / 1 atom = mass of a mole of atoms / 6.022 x 10^23 atoms.
mass of 1 atom = mass of a mole of atoms / 6.022 x 1023
mass of 1 N atom = 14 / 6.022 x 10^23 N atoms
mass of 1 N atom = 2.325 x 10^-23 g
The mass of a single Nitrogen atom is 2.325 x 10-23 g.
First convert the kg to g ----- 0.03kg = 30g
Then divide the mass by the volume ----- 30g ÷ 25mL = 1.2
The density is 1.2g/mL<span />

Hexavalent chromium are chemical compounds that has a chromium with an oxidation state of +6. It is commonly used in textile dyes and wood preservation to avoid corrosion and conversion coatings.</span>
the only process out of the four that does not happen in both animals implants would be photosynthesis. photosynthesis is when the cell takes the energy from the Sun's UV rays and turns into a form of energy that it can use
Answer:
Mechanical waves travel through matter, causing it to vibrate, expand and contract, move up and down, side to side, or in circles. They include water waves, sound waves, and seismic waves. ... They all travel at the same speed — the speed of light — in a vacuum, but when they come into contact with matter, they slow down.
