Dina computed the mass of 1,000 protons in grams. The calculator displayed the number 1.67E−21

. What is the mass of 1,000 protons in scientific notation

The mass of 1,000 protons in scientific notation is 1.67 × 10^-21 grams.

To write the mass of 1,000 protons in scientific notation, we can rewrite the number 1.67E-21 as:

1.67 × 10^(-21)

So, the mass of 1,000 protons in scientific notation is 1.67 × 10^(-21) grams.

To find the mass of 1,000 protons in scientific notation, we need to convert the given number 1.67E−21 into scientific notation.

Scientific notation is a way to express numbers as a product of a decimal number between 1 and 10, and a power of 10. In this case, it will be expressed as: a × 10^b, where 'a' is a decimal number and 'b' is the exponent.

For the given number 1.67E−21, we can see that the decimal part is 1.67 and the exponent is -21.

To rewrite it in scientific notation, we move the decimal point 21 places to the left (since the exponent is negative) and put it between the 1 and the 6.

Therefore, the mass of 1,000 protons in scientific notation is:

1.67 × 10^(-21) grams
