Mass is the weight of the compound or the molecule in a sample that is given in grams. The mass of sucrose in the sample is 171 gms.
<h3>What is mass?</h3>The mass of the compound is the product of the molar mass of the compound and the number of moles of the compound in a sample.
Given,
The molar mass (m.w.t) of sucrose = 342.3 g/mol
Number of moles (n) of sucrose = 0.500 moles
The mass of sucrose is calculated as:
Therefore. the mass of sucrose in the sample is option A. 171 gms.

Answer: The angle between the carbon-chlorine bonds in phosgene will be 120°
Explanation: Formula used to calculate the hybridization:
where,
V = number of valence electrons present in central atom i.e. carbon = 4
N = number of monovalent atoms bonded to central atom = 2
C = charge of cation = 0
A = charge of anion = 0
For
The number of electron pairs are 3 which means that the hybridization will be and the electronic geometry of the given molecule will be trigonal planar.
The bond angle in this electronic geometry is 120°
The structure of phosgene is attached below.
