Dina computed the mass of 1,000 protons in grams. The calculator displayed the number 1.67E21. What is the mass of 1,000 protons in scientific notation??
The mass of 1 proton is approximately 1.67 x 10^-24 grams. To find the mass of 1,000 protons, we multiply the mass of 1 proton by 1,000.
(1.67 x 10^-24 grams) x 1,000 = 1.67 x 10^-21 grams
Therefore, the mass of 1,000 protons in scientific notation is 1.67E-21 grams.
The mass of 1,000 protons in scientific notation is 1.67E21 grams.
To find the mass of 1,000 protons in scientific notation, we will start with the given number in normal notation, which is 1.67E21. This notation represents a number in the form of a decimal multiplied by a power of 10.
In this case, 1.67E21 means 1.67 multiplied by 10 raised to the power of 21. So, to convert it to scientific notation, we count the number of decimal places we need to shift the decimal point to the left or right to obtain a number between 1 and 10.
Starting with 1.67, we need to move the decimal point 21 places to the right to obtain a number between 1 and 10. Since we are moving the decimal point to the right, the power of 10 will be positive.
Thus, the mass of 1,000 protons in scientific notation is 1.67 x 10^21 grams.
