Answer:
n = 6.06 x 
mol
Explanation:
n =?
m = 3.06 x 10-³ g
M (H5) = 5 x 1.01 (Since we only want hydrogen)
Atomic mass of C = 12.01
Atomic mass of H is 1,01, etc.
Having this data, we can use the Molar mass formula and change it so we can know the quantity of matter (n) in moles, and we just replace it.
M = 
⇔ n = 
⇔ n = 
⇔ n = 6.06 x mol
Note: The numbers I've used may be different from yours, by a small difference. I don't know if it's the case, but hope it helped.
Answer: 40 + 2x14 + 6x16 = 164g/mole
54.3g x [1mole / 164g] = 0.331moles
355mL x 1L / 1000mL = 0.355L
molarity = 0.331moles / 0.355L =
00
Explanation:
Relatively few hydrogen atoms
Answer:
1,2,1,2
Explanation:
You would need only one of the CH4 but 2 of the O2 then 1 CO2 and 2 H2O on each side of the equation you now have 1 carbon, 4 hydrogen, and 4 oxygen.
1 mol ------------ 6,02×10²³
0,17 mol ------- X
X =(0,17×6,02×10²³)/1
X = 1,0234×10²³ molecules H₂O
