The molar mass of the imaginary compound Z(AX₃)₂ is the sum of the molar mass of Z, A and X.
<h3>How do we calculate molar mass?</h3>
Molar mass of any compound will be calculated by adding the mass of each atoms present in that compound.
Given compound is Z(AX₃)₂, molar mass of the given compound will be calculated as:
Molar mass of Z(AX₃)₂ = Molar mass of Z + molar mass of 2(A) + molar mass of 6(X)
Hence molar mass of Z(AX₃)₂ is the sum of the masses of all atoms.

Answer: Option (B) is the correct answer.
Explanation:
When two circles are of same same then they are known as congruent circles.
Whereas a rectangle is a kind of parallelogram with all sides equal to 
.
Therefore, when 2 congruent circles and 1 rectangle combines then it results in the formation of a cylinder.
Thus, we can conclude that solid formed when 2 congruent circles and 1 rectangle combines will be a circle.

Explanation:
<em>A chemist adds 1.55 L of a 0.00582 M calcium sulfate solution to a reaction flask. Calculate the mass in grams of calcium sulfate the chemist has added to the flask.</em>
Step 1: Given data
- Volume of the solution (V): 1.55 L
- Molar concentration of the solution (C): 0.00582 M (0.00582 mol/L)
Step 2: Calculate the moles (n) of calcium sulfate added
We will use the following expression.
n = C × V
n = 0.00582 mol/L × 1.55 L
n = 0.00902 mol
Step 3: Calculate the mass corresponding to 0.00902 moles of calcium sulfate
The molar mass of calcium sulfate is 136.14 g/mol.
0.00902 mol × 136.14 g/mol = 1.23 g
