The mass of one mole of water it is 18 amu, but you need to find the mass of a molecule of water, therefore you calculate the mass of one mole of water, which is 18 amu and you divided by Avogadro's number which is 6,022 x 10^23. The result is 2,989 x 10^-23. Hope I helped you. If you have any questions ask :) Good luck.
Answer:
I'd say the answer is B) Load.
Hope this helps. :-)
Answer:
<em>0.15M</em>
Explanation:
Molar Concentration =
Assuming 20g of the unadulterated aluminium chloride was weighed into the volumetric flask, and given molar mass of AlCl3 = 133.34g/mol
∴ Molarity =
= 0.14999 ≈ <em><u>0.15M (to 2 significant figures)</u></em>
I hope this solution is clear. The same can be calculated from concentration by volume.
