How Many Molecules are in 1 g of Sugar?

Explanation:

Hello!
Let's solve this!

To write a number in scientific notation, we look for a number between zero and nine. Then we count the number of times we move the decimal point to reach that number. If we move the decimal point to the right, the exponent is negative. If we move the decimal point to the left, the exponent is positive.

In this case, the number is: 1 760 000 000 000 000 000 000.

We choose the number 1.76 and move the decimal point 21 times to the left, so the exponent is positive.

The solution is 1.76 x 10^21.

The correct answer is option C.
