In between 45% to 70%.
Explanation:
Find the given attachment.
Answer:
NH₃ = 17.03 g/mol
Explanation:
Molecular weight is calculated by adding the atomic mases of all the atoms present in a molecule.
Like in case ammonia three hydrogen atoms and one nitrogen atom are present.
1 H = 1.01 g/mol
1 N = 14 g/mol
NH₃ = 14 + (1.01×3)
NH₃ = 17.03 g/mol
Answer:
A
Explanation:
the average kinetic energy of all the atoms or molecules of that substance.
Answer:
The solution can be prepared by adding 150.0 mL of isopropyl alcohol to 350.0 mL of water to make 30.0% isopropyl alcohol aqueous solution.
Explanation:
∵ The volume% of a solution = [(volume of the solute(isopropy)/(volume of the solution)] x 100.
The volume % = 30.0%, volume of the solution = 500.0 mL.
∴ Volume of the solute = (the volume% of a solution)(volume of the solution)/100 = (30.0%)(500.0 mL)/100 = 150.0 mL.
∵ The volume of solution = volume of the solute + volume of water
∴ Volume of water = volume of the solution - volume of the solute = (500.0 mL) - (350.0 mL) = 150.0 mL.
- <em>So, the solution can be prepared by adding 150.0 mL of isopropyl alcohol to 350.0 mL of water to make 30.0% isopropyl alcohol aqueous solution.</em>
In periodic table, size increases from top to bottom and will decrease from left to right.
So the order will be :
- Rubidium
- Calcium
- Selenium
- Sulfur
- Chlorine
- fluorine
hope this helps
