The weight of the object is 15.12 grams.
The density of the object is calculated by dividing the mass by the volume. So, density = mass/volume = 12g/4ml = 3 g/ml.
3 teaspoon
it depends. 6mm is refuring to the bbs size. 12g is describing the weight of an bb
The molecular weight of sodium hydroxide is 40g/mol. To get the amount of moles, you have to divide the weight by molecular mass. 12g / 40 is 0.3 moles. This is 300 millimoles.
What is your question?
12g-9 = 3
density=mass divided by the volume 12g divided by 27 the volume = 0.4
It is: 12g+9g = 21g
Unless you have a scale or the packaging, its not like they label them so you can't. Usually it's a .12g bb if you can see the seam, because no one would buy a high quality .12g bb.
Density = mass ÷ volume = 12g ÷ 3cm3 = 4 g/cm3
Density = Mass/Volume = 12/8 = 1.5 grams per cm3
12g is 12/14, or 6/7, of 14g.
