Express each of the following in standard form:

Mass of a molecule of hydrogen gas is about 0.00000000000000000000334 tons.

Given that, Mass of a molecule of hydrogen gas = 0.00000000000000000000334 tons


Standard form = 0.334 × 10-20 tons


= 3.34 × 10-1 × 10-20


Using the law of exponent,


= 3.34 × 10-1-20


= 3.34 × 10-21


∴ The standard form is 3.34 × 10-21 tons
