The mass of Ca(CN)2 : 92,11 g/mol
<h3>Further explanation</h3>
Given
0.0321 moles of Ca(CN)2
Required
The mass
Solution
The mole is the number of particles contained in a substance
1 mol = 6.02.10²³
Moles can also be determined from the amount of substance mass and its molar mass
mol(n) = mass(m) : MW(molecular weight)
Input the value :
mass = mol x MW Ca (CN)2
mass = 0.0321 x 92,11 g/mol
mass = 2.957 g
Explanation:
Br2 + S2O32- + 5H2O –> 2Br- + 2SO4 + 10H+ + 6e
Kilograms and grams. They're both commonly used to measure mass.

A. Refracted
Explanation:
Incident rays parallel to the optical axis are reflected from the mirror.
Answer:
Al+3
Explanation:
Ion is a positively or negatively charged species. A neutral species does not carry any charge.
here only Al has +3 charge. So it is an ion.
