3.2 g KClO3
Explanation:
1.1 g C12H22O11 × (1 mol C12H22O11/342.3 g C12H22O11)
= 0.0032 mol C12H22O11
0.0032 mol C12H22O11 × (8 mol KClO3/1 mol C12H22O11)
= 0.026 mol KClO3
Therefore, the minimum amount of KClO3 needed is
0.026 mol KClO3 × (122.55 g KClO3/1 mol KClO3)
= 3.2 g KClO3
Answer:
The third one from the left–the graduated cylinder.
Explanation:
The laboratory apparatus that gives an <em>"accurate" </em>or <em>"precise" </em>measurement of a liquid's volume is the<em> graduated cylinder</em>. All you have to do is to pour the liquid into the cylinder and read its measurement using the calibrated scale.
The graduated cylinder comes in different sizes, which means the scale divisions will depend on its size. When reading the measurement, it is important to take note to read at the <u><em>bottom of the meniscus</em></u> because it gives the most accurate volume.

Answer: 1.46moles
Explanation:
Applying PV= nRT
P= 1atm, V= 32.6L, R= 0.082, T = 273K
Substitute and simplify
1×32.6/(0.082×273)=n
n= 1.46moles
