To calculate the mass of 1 trillion atoms, we need to know the atomic mass of the element in question. Each element has a different atomic mass, which is expressed in atomic mass units (amu).
Let's assume we are considering a single element and use the atomic mass of carbon as an example. The atomic mass of carbon is approximately 12.01 amu.
To calculate the mass of 1 trillion atoms of carbon, we can follow these steps:
Convert 1 trillion atoms to moles: 1 trillion = 1,000,000,000,000 (1 followed by 12 zeros) 1 trillion atoms / Avogadro's number ≈ 1 trillion / 6.022 × 10^23 ≈ 1.66 × 10^(-14) moles
Calculate the mass in grams: mass (grams) = moles × atomic mass mass (grams) = 1.66 × 10^(-14) moles × 12.01 amu
Using these calculations, the mass of 1 trillion carbon atoms would be approximately 1.99 × 10^(-13) grams.
It's important to note that the atomic mass and resulting mass will vary depending on the element you are considering.
