Final answer:
To convert the mass of a grain of sand from kilograms to grams, multiply by 1000, resulting in a mass of 9 times 10⁻⁵ grams in standard form.
Explanation:
The average mass of a grain of sand from a certain beach is 9 times 10⁻⁸ kilograms. To convert this value to grams, we use the conversion factor where 1 kilogram equals 1000 grams. Therefore, to convert the mass of a grain of sand to grams, we multiply by 1000.
In standard form, the conversion is as follows:9 times 10⁻⁸ kg * 1000 g/kg = 9 times 10⁻⁵ g.
This value in grams in standard form is 9 times 10⁻⁵ grams.
