0.90g /cm^2
Density is a value for mass, such as kg, divided by a value for volume, such as m3. Density is a physical property of a substance that represents the mass of that substance per unit volume. To calculate for the density of the unknown metal, we simply divide the mass of the substance by the volume measured. We do as follows:

Density = mass / volume
Density = 222.50 g / 25 mL
Density = 8.9 g/mL

Find the total mass of three diamonds that have masses of 14.2 grams, 8.73 grams, and 0.912 gram
GaryK [48]
The total mass means that you need to add up all three diamonds' mass. So the calculation equation is 14.2+8.73+0.912 = 23.842 g.

What is the wavelength of light that has a frequency of 2.85 x 10^14 Hz [c=3.00 x 10^8]
aniked [119]

Answer:

1.05 x 10^-6

Explanation:

Lambda = c / f

f if frequency

c is intensity of light

lambda = 3 x 10^8  / 2.85 x 10^14

             = 1.05 x 10 ^-6
