Question
The mass of one hydrogen atom is 1.67×10−241.67×10−24 gram. Find the mass of 80,000 hydrogen atoms. Express the answer in scientific notation.
Solution
To find the mass of 80,000 hydrogen atoms, you need to multiply the mass of one hydrogen atom by the number of atoms.
Step 1: Identify the mass of one hydrogen atom, which is given as 1.67×10^-24 grams.
Step 2: Multiply this mass by the number of atoms, which is 80,000.
Mathematically, this is represented as:
(1.67×10^-24 grams/atom) * (80,000 atoms)
Step 3: Perform the multiplication.
The result is 1.336×10^-19 grams.
So, the mass of 80,000 hydrogen atoms is 1.336×10^-19 grams.
