Answer:
2.8g/cm³
Explanation:
Given parameters:
Mass of cube = 42g
Volume of cube = 15cm³
Unknown:
Density of the cube = ?
Solution:
Density is defined as the mass per unit volume of a substance. It is mathematically expressed as:
Density = 
So;
Density = 
= 2.8g/cm³
Answer:
The answer to your question is Magnesium Perchlorate
Explanation:
IUPAC Rules to name ternary salts of chlorine
1.- Ternary salts use prefixes and suffixes it depends on the number of oxygens they have.
Example
Metal + Chlorine + 1 oxygen = Name of the metal + hipo chlor + ite
Metal + Chlorine + 2 oxygens = Name of the metal + chlor + ite
Metal + Chlorine + 3 oxygens = Name of the metal + chlor + ate
Metal + Chlorine + 4 oxygens = Name of the metal + per + chlor + ate
For this compound the name is Magnesium Perchlorate.
Answer: 1.99 mol h20
Explanation:
you have 36.030 g, trying to get it into mols
to get from g to mols, use the molar mass (periodic table)
36.030 g h20 (1 mol/18.02g) = 1.99 mol h20
