We will need to know Avogadro's number and the molar mass of sucrose for this problem to do dimensional analysis.
- Avogadro's number: 6.022 × 10²³ molecules
- Molar mass of sucrose: 342.2965 g/mol
250g × 
× 
= 4.398 molecules
There are <em>4.398 sucrose molecules </em>in 250 grams of sucrose.
Answer:
0.5851 g/cm3
Explanation:
(45.62) ÷ (4.272)³ = 0.5851
Positive or negative charge
A polyatomic ion is a cluster of covalently bonded atoms with a positive or negative charge that acts as a unit.
A polyatomic ion is a covalently bonded groups of atoms that acts as a single unit and has a positive or negative charge as a result of the formation of an ionic bond with another ion. An example of a polyatomic ion is hydroxide ion which has the chemical formula; OH− (has a charge of −1), and is made up of one oxygen atom and one hydrogen atom.
Honestly, its based on your preference but the best recommended one would be loam. I use loam too, and it is really good for growing the plants.
