According to Avogadro's law 1 mole of a substance contains 6.022×10^23 particles.
Thus, 1 mole of sugar contains 6.022×10^23 molecules
Hence, 3 moles of sugars will contains;
= 3 ×6.022 ×10^23 molecules
= 18.066 ×10^23 molecules
≈ 18.1 ×10^23 molecules
<span>You are given a solid (A) that is soluble in water of 1g per 100ml of water at room temperature and 10g per 100ml of water at the boiling point. A is 90.1%.</span>
The correct answer is option 1. Butane and 2-butene have the same total number of carbon atoms. They both have four carbon atoms. They differ in there structure since the latter has double bonds on it. As a result of the different structure, they also have different properties.
Answer:
109.5°, 120°, 109.5°
Explanation:
The bond angles that are marked as a, b and c in the given molecules is in the order of :
Angle a : 109.5°
Nitrogen is 
hybridized and the geometry is tetrahedral. So the bond angle is 109.5°
Angle b : 120°
Carbon is 
hybridized, so the shape is trigonal planer and the bond angle is 120°
Angle c : 109.5°
Carbon is hybridized and the geometry is tetrahedral. The bond angle is 109.5°
