even the mass & volume will help .
mass: 8.32 g
density .832 g/mL
like about 9 or 10 hours. Or a lot more if you use a wipe.
it is prefferable to use 10/30 oil mixture because it doesn't harm the motor and the mixture's density is proper
Density of Transformer Oil at 29.5oC is 0.89g/cm3.The exact density of transformer oil depends upon the manufacturer but, expressed in SI units, is typically a little less than 900 kg/m3 at 20oC. The J&P Transformer Book states that 'a limit of 895 kg/m3 at 20oC ensures that the temperature (of the oil) must fall to -20oC before the density of the oil would exceed that of ice' -thus ensuring that if ice forms, then it would remain at the bottom of the tank.

Let us use the formula for computing the density. That one is mass/ volume. Given mass is 23g. In kg that will be 23 x 10-3 kg. Volume is 25 ml ie 25 x 10-6 m3. Plugging these to get the density it comes to 0.920 x 103 kg m-3 or 920 kg m-3
The density of actinium is 10 g/cm3.
The density of actinium is 10 g/cm3.
Density = grams/milliliters Density = 10 g/10 ml = 1.0 g/ml
The volume must be determined; try the method of liquid displacement using an anhydrous mineral oil.
A material's ability to float or sink depends on its density and the density of the liquid that it is in. Anything that has a greater density will sink in a liquid with a lower density. In order for oil to sink in water, oil has to have more density than water.Oil is typically less dense than water and so it will float above the water. Since density is mass divided by the volume, theoretically, we can increase density by squishing all of the oil together to decrease the volume (but this is not feasible, maybe next to impossible). Another way to do it is to heat both of the oil and the water. When heated, most materials decreases their density but not at the same rate because of the difference in material properties. Certain oils has a low coefficient of expansion. And so, when heat is added to the water and the oil, the oil density will remain close to its original value while the water density decreases. Once the water density is lower than that of oil density, the oil will sink.In short, oil could sink in water, but as a general rule, oil will float on water.
The weight can vary. Heavy oil weighs more than light oil. To determine the weight, we need to know the density of the oil, which is given as degrees API. Density in pounds per gallon = 141.5/(131.5 + API) *62.4 So a heavy oil. (10 degrees API for example) , has a density of 62.4 pounds per gallon, and one gallon weighs 62.4 pounds. A medium weight oil (30 degrees API for example) has a density of 54.7 pounds per gallon and one gallon weights 54.7 pounds. A light weight oil (50 degrees API for example) has a density of 48.6 pounds per gallon and one gallon weights 48.6 pounds. The density units of API stand for the American Petroleum Institute. I note that a density of 10 deg API is the same as the density of water, below 10 degrees, the oil will sink. I also note that if double the API density, I do not double the density of the oil as measured in pounds per gallon.
Most readily available bio-diesels are about 90% diesel and 10% vegetable oil. So no, wont hurt.
