Trigonal planar. Hope that helps!
60 I think bcz if there is 1&2 they differ 10 times
Answer:
9.033 × 10²³ molecules
Explanation:
Given data:
Mass of oxygen = 48.0 g
Number of molecules = ?
Solution:
Number of moles of oxygen:
Number of moles = mass/molar mass
Number of moles = 48.0 g/ 32 g/mol
Number of moles = 1.5 mol
Avogadro number:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ molecules
1.5 mol × 6.022 × 10²³ molecules / 1mol
9.033 × 10²³ molecules
n = Number of Moles
S is the symbol for Sulfur
t is usually temperature
+ and - are the charges of molecules
If they're next to each other, it means it's multiplication, or combined elements (molecules)
