I think it's more than 100,000 mold
Dear friend,
How are you doing? I finally switched to my new school and it's been so hard adjusting. But I know I have a new chance at making new friends and memories. Also, I can learn new things, like interacting with new people and how to keep my anxiety low. I really miss us hanging out and how much we'd laugh and get in trouble at class. But i really hope to see you soon & that it hasn't gone terribly wrong for you since i left.
your friend,

Answer: Multiple covalent bonds may occur in atoms that contain carbon,nitrogen, or <u><em>oxygen</em></u>.
The mass of sodium chloride used <u>was 1.17 grams</u><u>.</u>
The mole fraction can be calculated by way of dividing the number of moles of 1 factor of an answer via the full variety of moles of all the additives of an answer. it is mentioned that the sum of the mole fraction of all the components inside the solution has to be the same as one.
mass of NaCl given = 64.9 g
mole = mass/molar mass
= 64.9 / 58.5
=<u> 1.109</u>
a mole fraction of water = 0.980
mole fraction of NaCl = 1 - 0.980
= <u>0.02</u>
1 mole of NaCl = 58.5
mass of NaCl = 58.5 × 0.02
=<u> 1.17 gram</u>
Mole Fraction describes the range of molecules contained within one aspect divided through the whole range of molecules in a given combination. it's miles quite beneficial whilst two reactive-natured components are mixed collectively.
