Answer:
Molarity = 8.89 mol/L
Explanation:
Given data:
Mass of hydrogen peroxide = 3%
Density = 1.01 g/mol
Molarity = ?
Solution:
3% hydrogen peroxide means 3 g of H₂O₂ are present in 100 g of solution.
Now we will calculate the moles of H₂O₂.
Number of moles = mass / molar mass
Number of moles = 3g/ 34 g/mol
Number of moles = 0.88 mol
Now we calculate the volume of solution.
d = m/v
v = m/ d
v= 100 g/ 1.01 g/ mL
v = 99 mL
In Litter
v = 99 / 1000 = 0.099 L
Molarity:
Molarity = number of moles / volume in L
Molarity = 0.88 mol/ 0.099 L
Molarity = 8.89 mol/L
Answer:
False
Explanation:
In physical change chemical composition stay the same, does not change.
Answer:
The primary function of chemical nomenclature is to ensure that a spoken or written chemical name leaves no ambiguity concerning which chemical compound the name refers to: each chemical name should refer to a single sub
You should test several properties because some minerals might be similar, but if you test all the properties, you will identify it correctly.
