two
three
four

two

Explanation:

Every observer would observe the same image location and every light ray would follow the law of reflection. Yet only two of these rays would be needed to determine the image location since it only requires two rays to find the intersection point.

pls name braainly :)

The answer is: 4.71 grams of Hydrogen

From the statement, we know that for the studied compound, which has a mass of 124 g, we have that 3.80% is Hydrogen.

So, to find how many grams of Hydrogen is in 124 grams of the compound, we need to do the same calculation:

First, we need to convert the 3.80% percent in a real number, we can do it by dividing the percent into 100:

Then,

So, there are 4.71 grams of Hydrogen in 124 grams of the compound.

Have a nice day!
