What is the molar concentration of h3o+ in a cola that has a ph of 4.240?

Chemistry
1 answer:
Andreyy893 years ago
6 0

The pH is calculated using the expression: pH = - log [H3O+].  
 To find the concentration of [H3O+] 
 [H3O+] = 10^(-pH)  
 Solving the RHS we have 10^(-4.240) = 0.1440 
 Hence the concentration of H3O+ is 0.1440.

What is diabetes? How does it disrupt normal cellular activities? What are the overall consequences for your body?
Vlad1618 [11]

Answer:

Diabetes is a group of diseases that affect how your body uses blood sugar (glucose). Glucose is vital to your health because it's an important source of energy for the cells. Cells are everywhere including the blood, bones and muscles. When you have diabetes, you don’t have enough insulin in your blood (an organ in your body called the pancreas makes insulin). Insulin controls the movement of blood sugar into the cells of the body.

Write the following numbers in standard notation. Use a terminal decimal point when needed.
maw [93]

In this case, when converting scientific notation to standard notation, we simply have to multiply the given number by 10^{x}x.

The answer will be 7.510^{2}  = 7.5100 = 750

A standard notation is a form of writing a given number, an equation, or an expression in a form that follows certain rules. For example, 4.5 billion years is written as 4,500,000,000 years.
