Rearrange the following equation and solve for x when the hydrogen ion concentration is 0.1 m. ph=5+logx (recall that ph=−log[h+]. use the hints if you do not obtain one of the answers.) view available hint(s) rearrange the following equation and solve for when the hydrogen ion concentration is 0.1 . (recall that . use the hints if you do not obtain one of the answers.) x=0.50 x=1×10−3 x=1 x=1×10−4

x=1×10−4

Step-by-step explanation:

we have

-----> equation A

The pH of a given solution is the negative log base  10  of the concentration of hydrogen ions,  H+

so

ph=-log[H+]  

In this problem we have the concentration of hydrogen ions

[H+] =0.1 M

That means that the pH of the solution will be

ph=-log[0.1]  

Rewrite

ph=-log[10^-1]  

ph=-(-log10)

Remember that

log10=1

substitute

ph=-(-1)

ph=1

substitute the value of ph in equation A and solve for x

applying property of logarithms

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
