Density = Mass/Volume = 4.2 units of mass/2units of volume = 2.1 units of mass per unit of volume.
Density = (mass) / (volume) = 42/28 =1.5 gm/cm3
Density = (mass)/(volume) = 128/4 = 32 gm per ccNote: That's a remarkable substance you've got there. It's about 2.8 times as dense as lead,and about 42% denser than osmium ... the heaviest natural element. Don't drop it.
In the context of whiskey, "42 percent vv" refers to the alcohol by volume (ABV) percentage of the whiskey. ABV represents the amount of alcohol present in the total volume of the liquid. Therefore, a whiskey labeled as "42 percent vv" contains 42% alcohol by volume, meaning that 42% of the liquid is pure alcohol. This percentage is important for understanding the strength and potency of the whiskey.
Volume = pi*42*32 = 512pi cubic cm.
Volume = 1/3*pi*42*15 = 251.327 cubic units
Density = (mass) / (volume) = 42/28 =1.5 gm/cm3
Density of that object is 2.8
Density = (mass) / (volume) = 2.33 gram/cc(rounded)Note: The 'ml' and the 'cc' are identical volumes.
You would have to know the mass and the volume of your blue whale in order to find the density, or have the average density of the whale given to you. If you have the mass and the volume, then you can find the density using the equation D=mv, where D= Density, m=mass, and v=volume. Or, you can Douglas Adams it and say 42.
Density = (mass) divided by (volume) = (42) divided by (7) = 6 grams per cm3 . Next time, it'll be a lot easier if you just have your teacher contact us directly.
The density of the object would be 1.91 kg/m³ (density = mass/volume).
To calculate the weight of the fabric you should know the numbers of thread count and the yarn count. Use a thumb rule of thread count X 42/ yarn count to have the approximate weight of the fabric per mt.
Volume = 2.5 cm*42 cm*1.8 cm = 189 cm3 So density = mass/volume = 189/9.5 = 20 grams per cm3
D = m/V D = 56g/15ml D = 3.7g/ml
Volume of the object = 3cm * 7cm * 2 cm = 42 cm3 So density = mass/volume = 302.4/42 = 7.2 g per cm3
Density = Mass/Volume Density = 200g/125mL Density = 1.6g/mL ***If your instructor is checking for significant figures, then based on the numbers that you gave in the question, the answer should be 1.60g/mL.
The difference between the new volume and the old volume is 20 ml. This means that the 60.0 g piece of metal had a volume of 20 ml. Density is given by mass / volume, so this metal has a density of 3 g / 1 ml.
