The atomic mass of a chemical element is the number of protons + number of neutrons in each atom of that element—electrons are i

gnored. Examples The atomic mass of hydrogen (H) is 1 (1 proton) and that of helium (He) is 4 (2 protons + 2 neutrons).
The gram atomic mass of a chemical element is the atomic mass of that element in grams. Example The gram atomic mass of H is 1 gram and that for He is 4 grams.

Astounding Fact There are approximately 6 x 1023 atoms in the gram atomic mass of every known chemical element. Examples There are 6 x 1023 atoms in 1 gram of H and in 4 grams of He. Hence, there are 12 x 1023 atoms, or 1.2 x 1024 atoms, in 2 grams of H and in 8 grams of He.

Standard carbon is Carbon 12, abbreviated C-12. Its atomic number is 12 (6 protons and 6 neutrons) and its gram atomic mass is therefore 12 grams.

How many atoms are there in 96 grams of C-12? (Read the exponents carefully.)

(a) 1.2 x 1024 atoms (b) 12 x 1023 atoms (c) 4.8 x 1023 atoms

(d) 4.8 x 1024 atoms (e) 96 x 1024 atoms (f) none of the above

Given f(x) and g(x) = f(x + k), use the graph to determine the value of k.
dedylja [7]

g(x) is basically transformed f(x). First, let's focus on f(x) graph. Notice how the graph has slope of 1 and intersect y-axis at (0,0).

Which means that our equation for f(x) is:

\large{f(x) = x}

Now then we focus on g(x). g(x) is f(x+k). That means if f(x) = x then f(x+k) would mean substitute x = x+k in the equation.

\large{f(x + k) = x + k }\\  \large{g(x) = x + k}

Next, we want to find the value of k. In the slope-intercept form or y = mx+b where m = slope and b = y-intercept. Notice the g(x) graph and see that the graph intersects y-axis at (0,4). Therefore k = y-intercept = 4.

\large{g(x) = x + 4}

Answer

  • g(x) = x+4
  • Therefore the value of k is 4.
