Create a conversion factor from "<span>There are 6.02 × 10^23 atoms in 1 gram of hydrogen:"
6.02*10^23 atoms
-------------------------
1 gram
Then mult. 800 grams by this conversion factor:
</span>6.02*10^23 atoms 800 grams
------------------------- * ----------------
1 gram 1
This comes out to 4816*10^23 atoms, which, in scientific notation, is
4.816*10^26 atoms.
Answer: D
Step-by-step explanation:
Answer:
2x ( x + 5 ) ( x − 2 y )
Step-by-step explanation:
1) factor out 2x from the equation
2) factor out x from the equation
3) factor out -2y from the equation
4) factor out x + 5 from the equation
2x ( x + 5 ) ( x − 2 y )
Answer:
2. 4
Step-by-step explanation:
use the formula A=ab/2
a-leg 1
b-leg 2 (base)
since it is a right triangle the height would be 2 cm and the base would be the leg (4 cm)
plus into the equation- A= 2(4)/2
8/2=4
