2.0 L in mL :
2.0 x 1000 => 2000 mL
1.26 kg in g :
1.26 x 1000 => 1260 g
D = mass / volume
D = 1260 / 2000
D = 0.63 g/mL
hope this helps!
First convert volume to mass:
mass = 0.789 g/mL * 155 mL = 122.295 g
Then convert mass to number of moles:
number of moles = 122.295 g * (1 mole / 46 g) = 2.66 moles
Using avogadros number, we get the molecules:
<span>number of molecules = 2.66 moles * 6.022 x 10^23 molecules
/ mole = 1.6 x 10^24 molecules</span>
Carbon fiber is also known as "graphite fiber"
Answer:
True
Explanation:
An alcohol is an organic molecule containing an -O-H group. Any molecule which has a hydrogen atom attached directly to an oxygen or a nitrogen is capable of hydrogen bonding.
