Density is the mass of substance per unit volume of a substance. to solve the problem, first calculate the mass of the gas.
mass gas = ( mass of balloon with gas ) - ( mass of balloon )
mass gas = 10.24 g - 2.42 g
mass gas = 7.82 g
so the density
density = m / v = 7.82 g / 5470 cm3
density = 0.00145 g / cm3
Answer:
3 regions of high electronic density
2 simple links
1 double bond
Explanation:
Hello!
First we calculate the total valence electrons that make up the molecule (6 + 6 * 3 = 24)
We locate six electrons forming the bonds and complete the octecs with the remaining 18 electrons.
We move 2 electrons of an oxygen to complete the sulfur octet.
