Household hydrogen peroxide is an aqueous solution containing 3.0% hydrogen peroxide by mass. What is the molarity of this solution? (Assume a density of 1.01 g>mL.)

Molarity of this solution is 0.88 M

Explanation:

Molarity : It is defined as the number of moles of solute present in one liter of solution.

Formula used :

where,

Given : 3.0 g of hydrogen peroxide is present in 100 g of solution.

n = moles of solute =

= volume of solution in ml=

Now put all the given values in the formula of molarity, we get

Thus molarity of this solution is 0.88 M

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
