Answer:
Mass of proton (m) = 1.67×10^(-27) kg
Step-by-step explanation:
Mass of proton (m) = 1.67×10^(-27) kg.
Since, 1 kg = 1000 g
Therefore, m = 1.67x10^(-27+3) g = 1.67x10^(-24) g
Let N no. of protons be present in 1 g. Hence, Nxm = 1 g
So, N = 1 / m = 1 / (1.67x10^(-24))
N = 6x10^(23) (approx.)
Exact mass of proton gives N = 6.022 x 10^(23).
That is a very special no. In fact, it is the Avogadro’s constant used frequently in chemistry. Avogadro’s no. is actually the number of atoms in exactly 12 g of C-12 isotope of carbon. Since, the atomic mass of C-12 is 12 u (unified mass), then again the no. of carbon atoms turn out to be N.
Answer: 1/24
Step-by-step explanation:
If one fourth was split into six pieces, you would multipli six by one fourth to get 1.24==

Y= -2/3x +26/3
First find the slope of the given points. The use the opposite reciprocal for the new slope. Find the midpoint of the given points. Use this ordered pair with your new slope. Plug into y=Mc+b to find b. Then rewrite using the new m and b.
