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>
Mass and volume are two units used to measure objects. Mass- the amount of matter an object contains and volume- how much space it takes up
An Environmental Impact Study is used to provide a sufficient level of detail to demonstrate that a proposed development will have no negative impacts on the natural features or ecological functions of the subject and surrounding (“adjacent”) lands. Hope this helps!!!
The correct answer is A
The octet rule state that all main group elements form bonds such that they achieve a noble gas configuration with eight valence electrons. In this case carbon has 4 electrons in its outermost shell and requires 4 more electrons to achieve an octet. Hydrogen is an exception to the octet rule and it only requires two electrons to achieve an octet. All the other options have C and H forming bonds that do not lead to a noble gas configuration.
