Answer: 62.5 mL
Explanation:
The key thing you need to understand here is that chemical reactions depend on reactant particles bumping into each other collision theory
Given parameters:
mass of an empty beaker = 65gm
mass of the beaker and water = 165gm
volume of water = 100cm³
Unknown:
Density of water = ?
Solution:
Density is the mass per unit volume of a substance;
Density =
To find the mass of the water ;
Mass of water = Mass of beaker and water - mass of an empty beaker
= 165g - 65g
= 100g
So input parameters and solve;
Density =
Density of the water in the beaker = 1g/cm³
Answer:
The long form version is too wide to easily fit on a computer screen or sheet of paper
Explanation:
Using this equation, we can take 25/(1.0 + 19) and find that it is equal to 1.25 moles.
