Answer:
17. tie hair up
wear goggles
18. i don't know
19. you light it on the side of the box
20. it should be orange because that is the safest.
21. you turn down the electricity thing
Explanation:
The given data is as follows.
Initial concentration = 0.15 mg/ml,
Final concentration = 0.1 mg/ml, (as )
Final volume = = 0.1 ml
According to the dilution formula we get the following.
or, =
Putting the given values into the above formula we get the following.
=
=
= 0.0667 ml
=
= 66.7 microliter
This means that volume of protein stock which is required is 66.7 ml. Hence, calculate the volume of water required as follows.
Volume of water required = Total volume - volume of protein stock
= (100 - 66.7) microliter
= 33.3 microliter
Thus, we can conclude that we need 33.3 microliter of water and 66.7 microliter of protein.
Well, it introduced atoms in this world and their functions. When the theory of atoms were created many more theory's came and we slowly figure out what the atoms do and what their functions are. The theory of an atom really surprised people because most of the people never knew the possibility of having living things inside of them.
Hope this helps.
Answer: Atomic Mass
Explanation:
The Atomic mass of an atom is the number of protons and neutrons in the atom and is measured in atomic mass units (amu) but can still be measured in kilograms.
For example, if the number of neutrons in an atom is 8 and the number of protons is 6, the atomic mass of the atom is 14.
