The spinal cord is part of the central nervous system
Atomic <span>mass gold = 196.96 u.m.a
196.96 g ------------------ 6.02x10</span>²³ atoms
112 g ---------------------- ( atoms)
atoms = 112 x ( 6.02x10²³) / 196.96
atoms = 6.74x10²⁵ / 196.96
= 3.42x10²³ atoms
hope this helps!
Answer:
The answer to your question is C₂HO₃
Explanation:
Data
Hydrogen = 3.25%
Carbon = 19.36%
Oxygen = 77.39%
Process
1.- Write the percent as grams
Hydrogen = 3.25 g
Carbon = 19.36 g
Oxygen = 77.39 g
2.- Convert the grams to moles
1 g of H ----------------- 1 mol
3,25 g of H ------------- x
x = (3.25 x 1) / 1
x = 3.25 moles
12 g of C ---------------- 1 mol
19.36 g of C ---------- x
x = (19.36 x 1) / 12
x = 1.61 moles
16g of O --------------- 1 mol
77.39 g of O --------- x
x = (77.39 x 1)/16
x = 4.83
3.- Divide by the lowest number of moles
Carbon = 3.25/1.61 = 2
Hydrogen = 1.61/1.61 = 1
Oxygen = 4.83/1.61 = 3
4.- Write the empirical formula
C₂HO₃
Answer:
Neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen.
Explanation:
Because their electronic configurations have the same number of electrons in the outermost shell.
