How many moles of aluminum hydroxide are needed to react with 25 grams of sulfuric acid?

0.16 moles of Aluminum hydroxide are needed to react with 25 grams of sulfuric acid.

Explanation:

In order to find the number of moles we first need to write down the balanced equation as,

Now as mentioned above,For 3 moles of sulfuric acid , we need 2 moles of Aluminum hydroxide to balance the equation,

Thus we can balance it as,

Thus it is now clearly known that 0.16 moles of Aluminum hydroxide are needed to react with 25 grams of sulfuric acid.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
