Actually, the
uncertainty point is when we have to estimate one place smaller than what the
graduated cylinder can accurately read. So in this case, the smallest that we
can accurately read is given by the minor marks of 0.2 mL. So if it is in
between two minor marks we can only estimate the number, therefore the
uncertainty is +/- 0.1ml.
Answer:
2 moles for the first 2 questions and 100g of water
Explanation:
The number of moles of nitrate dissolved in water if 6.15 mole of strontium nitrate is : 12.3 moles
<u>Given data :</u>
Moles of strontium nitrate = 6.15 moles
<h3>Ionization of Strontium Nitrate </h3>
When strontium nitrate ( ) is placed in water it will dissociates into its ions because strontium nitrate is an ionic compound.
Next step : Represent the ionization of strontium nitrate
From the Stoichiometry of the chemical reaction
I mole of strontium nitrate = 2 moles of Nitrate ions
6.15 mole of strontium nitrate = 2 * 6.15
= 12.3 moles of Nitrate
Hence we can conclude that The number of moles of nitrate dissolved in water if 6.15 mole of strontium nitrate is : 12.3 moles.
