Select the equality for picograms and grams. 1g = 10 ^ 12 pg 1pg = 10 ^ 12 g 1g = 10 ^ 9 * pg; 1g = 10 ^ - 12 pg
1g = 10 ^ 9 pg
The correct equality for picograms (pg) and grams (g) is: 1g = 10^12 pg.
The correct equality for picograms (pg) and grams (g) is: 1g = 10^12 pg.
To understand how to derive this equality, let's break it down step by step:
1. The metric system uses prefixes to indicate the magnitude of a unit. In this case, "pico" (symbol: p) is the prefix denoting one trillionth (10^-12).
2. The base unit for mass in the metric system is the gram (g). So, 1g is equal to 1 gram.
3. To convert grams to picograms, we need to multiply by the appropriate conversion factor. Since "pico" is 10^-12, we multiply 1g by 10^-12 to get the equivalent in picograms.
Therefore, the correct equality is: 1g = 10^12 pg.
