B and C
Explanation:
The different types of motor nerves transmit information to and from muscles, and they connect to muscle fibers through the motor endplate.
Im no sure what it is i just love helping little boys out. at this age it gives me a thrill.
Volume = V = 250ml = 0.25 L
<span>M = 0.135M </span>
<span>Molar mass of AgNO3 = 108+14+3*16 = 170 </span>
<span>M = mole/V </span>
<span>mole = 0.135*0.25 = 0.03375 mole </span>
<span>mole = mass/molar mass </span>
<span>mass = 0.03375 * 170 = 5.7375 gr</span>
Answer:
There are 1.253*10²⁴ particles in 2.080 moles
Explanation:
Avogadro's number is called the number of particles that make up a substance (usually atoms or molecules) that can be found in the amount of one mole. In other words, Avogadro's number is the number of molecules that one mole of any substance contains. Its value is 6.023 * 10²³ particles per mole.
So, you can apply a rule of three as follows: if 1 mole has 6.023*10²³ particles, then 2.080 moles, how many particles does it have?
amount of particles= 1.253*10²⁴ particles
<u><em>There are 1.253*10²⁴ particles in 2.080 moles</em></u>
