The specific heat of a material gives the energy it takes to increase the temperature of one unit mass of the material by one unit temperature. The SI unit for specific heat is therefore .
The formula relating the energy required to raise the temperature of grams of a substance with specific energy by degrees is
The question provides the following information:
Apply the formula:
<span>The pH scale is a logarithmic scale. Each change of 1 unit in pH represents a 10-fold change in hydrogen ion concentration. As the pH gets smaller the hydrogen ion concentration gets larger. Since you have gone from pH 5 to pH 3 there is a 100-fold increase in [H+].
For pH = 5; [H+] = antilog 10^-pH = 1.0 x 10^-5 M
For pH = 3; [H+] = antilog 10^-pH = 1.0 x 10^-3 M
(1.0 x 10^-3)/(1.0 x 10^-5) = 1.0 x 10^2 hope this helps</span>
Answer:
it would be 53
Explanation:
because 4.00 L at 158kPa and 28c would be 53 grams of oxygine
