Answer:
I don't really know what that is so here is a picture of it
Explanation:
The wording of your question doesn't quite make sense, but a mole of an element has the same mass in grams as a single atom of that element has in amu. The mole is defined as 6.02 x10^22 things, whether they be atoms or molecules or even moles! 6.02x10^22 atoms of carbon has a mass of 12.01 g, and a single atom of carbon has a mass of 12.01 amu. Hope this helps!
Answer:
The answer is option B, that is, it has two oxygen atoms.
Answer:
0.119 moles
Explanation:
Given that,
Mass measured by Nurse Antonio is 7 grams of NaCl
To find,
The no of moles of NaCl
Solution,
The number of moles is given by

m is given mass
M is molar mass
For NaCl, molar mass is 23+35.5 = 58.5 grams
So,

Therefore, there are 0.119 moles of NaCl.
