How to convert Rontogram to Attogram
$$\text{Mass}_{\text{ag}} = \frac{\text{Mass}_{\text{rg}}}{1000000000}$$
Examples
Example 1
Convert $20.0\ \text{rg}$ to $\text{ag}$.
$$\text{Mass}_{\text{ag}} = \frac{20.0}{1000000000}$$
$$\text{Mass}_{\text{ag}} = 0.00000002$$
$$\therefore \ 20.0\ \text{rg} = 0.00000002 \ \text{ag}$$
Example 2
Convert $65.0\ \text{rg}$ to $\text{ag}$.
$$\text{Mass}_{\text{ag}} = \frac{65.0}{1000000000}$$
$$\text{Mass}_{\text{ag}} = 0.000000065$$
$$\therefore \ 65.0\ \text{rg} = 0.000000065 \ \text{ag}$$
Example 3
Convert $120.0\ \text{rg}$ to $\text{ag}$.
$$\text{Mass}_{\text{ag}} = \frac{120.0}{1000000000}$$
$$\text{Mass}_{\text{ag}} = 0.00000012$$
$$\therefore \ 120.0\ \text{rg} = 0.00000012 \ \text{ag}$$
Example 4
Convert $135.0\ \text{rg}$ to $\text{ag}$.
$$\text{Mass}_{\text{ag}} = \frac{135.0}{1000000000}$$
$$\text{Mass}_{\text{ag}} = 0.000000135$$
$$\therefore \ 135.0\ \text{rg} = 0.000000135 \ \text{ag}$$
Example 5
Convert $175.0\ \text{rg}$ to $\text{ag}$.
$$\text{Mass}_{\text{ag}} = \frac{175.0}{1000000000}$$
$$\text{Mass}_{\text{ag}} = 0.000000175$$
$$\therefore \ 175.0\ \text{rg} = 0.000000175 \ \text{ag}$$
