The density of gold is 19.3 g/cm3. What is this value in kilograms per cubic meter?
검증된 단계별 안내1
Understand the conversion factors: 1 gram (g) is equal to 0.001 kilograms (kg), and 1 cubic centimeter (cm³) is equal to 0.000001 cubic meters (m³).
Convert the density from grams per cubic centimeter to kilograms per cubic centimeter by multiplying 19.3 g/cm³ by 0.001 kg/g.
Convert the density from kilograms per cubic centimeter to kilograms per cubic meter by dividing the result by 0.000001 m³/cm³.
Combine the conversion steps: Multiply 19.3 by 0.001 to convert grams to kilograms, then divide by 0.000001 to convert cubic centimeters to cubic meters.
Express the final density in kilograms per cubic meter (kg/m³) using the conversion factors applied in the previous steps.

주요 개념
질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.
Density
Density is a measure of mass per unit volume, typically expressed in units such as grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³). It is a fundamental property of materials that indicates how much mass is contained in a given volume.

Intro to Density
Unit Conversion
Unit conversion involves changing measurements from one unit to another, using conversion factors. In this context, converting density from g/cm³ to kg/m³ requires understanding that 1 g/cm³ equals 1000 kg/m³, due to the conversion factors of 1 gram = 0.001 kilograms and 1 cm³ = 0.000001 m³.
