Density = Mass / Volume
Density = 2.0g / 5.0ml
Density = 0.4 g/ml
6 atoms of Cobalt.
4 atoms to Phosphate (PO4).
6 atoms to sodium.
6 atoms to Chlorine.
The coefficient is one factor that tells you how many atoms go to each atom/element, however, the subscript also influences this.
If the compound has parenthesis, then the subscript within the parenthesis remains untouched and does not affect the atoms.
Basically, to calculate the atoms is multiply the coefficient (number in front of the atom) by the subscript attached to the atom. If it's a compound such as Co3PO4, then make sure the coefficient affects the second atom as well.
Hope this helps!
Answer:
V = 364500 L, 476.748 yard³
Explanation:
Given that,
The dimensions of a room are 10 meters wide by 15 meters long and 8.0 ft high.
l = 10 m, b = 15 m, h = 8 ft = 2.43 m
The volume of the room is :
V = lbh
So,
V = 10×15×2.43
V = 364.5 m³
As 1 m³ = 1000 L
364.5 m³ = 364500 L
Also, 1 m³ = 1.30795 yard³
364.5 m³ = 476.748 yard³
Hence, this is the required solution.
