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 1.67E-21 grams.
The mass of 1 proton is approximately 1.67 x 10^-24 grams. To find the mass of 1,000 protons, we can multiply the mass of 1 proton by 1,000.
(1.67 x 10^-24 grams) x (1,000 protons) = 1.67 x 10^-21 grams
Therefore, the mass of 1,000 protons is 1.67 x 10^-21 grams in scientific notation.
To find the mass of 1,000 protons in scientific notation, you need to convert the given value of 1.67E-21 into scientific notation. Here's how you can do it:
1.67E-21 can be rewritten as 1.67 × 10^(-21).
Now, let's calculate the mass of 1,000 protons in scientific notation:
Since we have 1 proton with a mass of 1.67 × 10^(-24) grams, we can calculate the mass of 1,000 protons by multiplying the mass of a single proton by 1,000:
1,000 protons × (1.67 × 10^(-24) g/proton) = 1.67 × 10^(-24) g × 1,000.
Multiplying these two numbers gives us:
1.67 × 10^(-24) g × 1,000 = 1.67 × 10^(-24+3) g = 1.67 × 10^(-21) g.
Therefore, the mass of 1,000 protons in scientific notation would be 1.67 × 10^(-21) grams.
