In chemistry class, Carlos calculated the number of molecules in 100 moles. The calculator displayed the number 6.0225. What is the number of molecules in 100 moles in scientific notation? (1 point)
O 6.02 × 1025
O 6.02 × 25
O 6.02 + 1025
• 25 x 100.03
The number of molecules in 100 moles in scientific notation would be 6.02 × 10^25.
To convert a number to scientific notation, we need to move the decimal point until there is only one digit to the left of it. In this case, we have 6.0225 as the number and we need to have 6.02 as the number with one digit to the left of the decimal point.
To achieve this, we need to move the decimal point two places to the right. This means we will multiply the number by 10 raised to the power of 2.
So, the number of molecules in 100 moles in scientific notation is 6.02 x 10^2. Therefore, the correct answer is O 6.02 × 10^25.
To express a number in scientific notation, you need to write it in the form of a x 10^b, where "a" is a decimal number between 1 and 10, and "b" is an integer that represents the power of 10.
In this case, the number Carlos calculated is 6.0225. To convert it to scientific notation, you need to move the decimal point four places to the right to obtain a number between 1 and 10. So, it becomes 6.0225 x 10^4.
However, since 100 moles is a larger quantity, you need to adjust the exponent accordingly. The number of molecules in 100 moles should have an exponent of 23 (10^23), because there are 6.0225 x 10^23 molecules in 1 mole.
Therefore, the number of molecules in 100 moles in scientific notation is: 6.0225 x 10^23.
Hence, the correct answer is: 6.0225 x 10^23 (6.02 × 10^23).
