The density of hydrogen is 8.2×10_5g/cm. Argon is 20 times as dense as hydrogen. Find the density of argon giving your answers in standard from correct to 3sf
To find the density of argon, we first need to find the density of hydrogen.
The given density of hydrogen is 8.2×10^(-5) g/cm.
Since argon is 20 times as dense as hydrogen, the density of argon is:
Density of Argon = 20 * Density of Hydrogen
= 20 * 8.2×10^(-5) g/cm
Calculating this value gives us:
Density of Argon = 1.64×10^(-3) g/cm
Rounding this value to three significant figures gives us:
Density of Argon = 0.00164 g/cm³
