Memorising the apperaranve the a distinctive flower, is no the best easy come prove something, since you could have just seen the summary in a book, and it is least likely you will certainly be believed.
A sample the Manganese (II) chloride has actually a fixed of 19.8 grams prior to heating, and also 12.6 grams after ~ heating till all the water is
no. The water molecules linked to every molecule of
Difference in fixed of
= 19.8 - 12.6 = 7.2 g
Difference in mass synchronizes to fixed of water moved out.
Molar mass of water = 18 g/mol
No. Of moles of water =
Mass of anhydrous
Molar massive of
No. That mol the anhydrous
0.1 mol that
1 mol that
Hence, no. Of water molecules associated to each molecule that
