Molar mass H₂SO₄ = 98.0 g/mol
Volume = 1.290 L
number of moles:
153.3 / 98 => 1.564 moles
M = n / V
M = 1.564 / 1.290
M = 1.212 mol/L

Negative electrons are attracted to the positive nucleus. This force of attraction keeps electrons constantly moving around the nucleus. The region where an electron is most likely to be found is called an orbital. Electrons are located at fixed distances from the nucleus, called energy levels.
So i believe the answer you’re looking for is, Orbitals.
Answer:
2.64gram
Explanation:
Molarity, which refers to the molar concentration, is calculated thus:
Molarity = number of moles (n) ÷ volume (L)
According to the question, volume = 100 mL, molarity = 0.240 M.
Since 1L = 1000mL
100 mL = 100/1000
= 0.1L
Hence;
0.240 = n/0.1
n = 0.1 × 0.240
n = 0.024mol
Mole = mass/molar mass
Molar mass of CaCl2 = 40 + 35.5(2)
= 40 + 71
= 111g/mol
mass = molar mass × mole
mass = 110 × 0.024
Mass = 2.64gram
