The solution for this problem would be:
H + ions from pH = 4.0 x 10^-4 moles.
But H2SO4 gives off 2 moles of H+ ions / mole.
Moles of H2SO4 = 2.0 x 10^-4
Mass = 2 x 10^-4 moles x 98 = 1.96 x 10^-3 grams
1.96 x 10^-3 grams / 10^3 = 1.96 x 10^-6 Kg.
Answer:
The answer is
<h2>0.63 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 47 g
volume = 75 mL
The density is
We have the final answer as
<h3>0.63 g/mL</h3>

They show the properties in between the metal and non-metals.
It is the atomic number of the element, which is <span>the number of protons in the nucleus of an atom that determines the chemical properties of an element. </span>
There is Kinetic energy involved in the state something is in. The molecules in a liquid are moving around quicker than those in a solid.
That's one reason.
The ice requires energy to melt. Bonds must be broken to get from a solid to a liquid.
