An atom of gold has a mass of approximately 3.25 times 10^-22 grams. What is the mass of 3000 atoms of gold?
3.25*10^-22 * 3*10^3 = ?
Hint: When multiplying/dividing, the exponents are added/subtracted respectively.
To find the mass of 3000 atoms of gold, we need to multiply the mass of one atom by the number of atoms.
Given:
Mass of one atom of gold = 3.25 x 10^-22 grams
Number of atoms = 3000
To calculate the mass of 3000 atoms of gold, we can use the following formula:
Mass = Mass of one atom x Number of atoms
Substituting the given values into the formula:
Mass = (3.25 x 10^-22 grams) x 3000
Now, let's calculate it:
Mass = (3.25 x 10^-22) x (3 x 10^3)
= 9.75 x 10^-19 grams
Therefore, the mass of 3000 atoms of gold is approximately 9.75 x 10^-19 grams.
To find the mass of 3000 atoms of gold, we first need to determine the mass of a single atom of gold, and then multiply it by 3000.
Given that an atom of gold has a mass of approximately 3.25 times 10^-22 grams, we can write this as 3.25 x 10^-22 g.
To find the mass of 3000 atoms of gold, we will multiply the mass of a single atom by 3000:
3.25 x 10^-22 g * 3000 = 9.75 x 10^-19 g.
Therefore, the mass of 3000 atoms of gold is approximately 9.75 x 10^-19 grams.
