mass of a teaspoon 50kg     or      5kg       or         50g?

50 grams still seems high, but definitly not any  kilogram. \n1 kg = 2.2 pounds

ya you would just go density divided by the mass and then you get the volume  make sure you density is grams/ml and then your mass should be ml and then your volume would turn out to be grams. good luck

No conversion is necessary.  36 ug/l equals 36 ng/ml, the ratio is the same!

Latent heat of vaporisation of water is 2260 kJ per kg, in other terms, 2260J per gram of water.  So if you have 50g of water, all you have to do it multiply 2260 by 50 to get the amount of heat that has to be absorbed.\n\nNote that the specific latent heat of vaporization is the amount of heat required to convert unit mass of a liquid into the vapour without a change in temperature.

Latent heat of vaporization of water is 2260 kJ.kg-1.\nConverting 50g to kg = 50/1000= 0.05kg\n\nTherefore 2260 KJ/KG x 0.05KG = 113 KJ or Kilojoules or 113,000 J or Joules is your answer

Well if you know the density of ANY two liquids and the overall weight, you ought to be abler to calculate the proportions:\n\nEG:\n\nWe have X amount of liquid with a SG of 1.2\nWe have Y amount of liquid with an SG of 1.6\nWe also know there is perhaps 3 litres and it weighs 1.4 Kg\n\n1.2 * x + 1.6 * Y = 1.4 * 3\nSimplifies\n\n12x + 16y = 14x3 (42)\n\n12x +16y = 42\n6x +8y = 21\n\nNow do basic algebra to find the proportions of the two.

If 3% is taken from MASS (which is not written clearly) and the liquid of solution is WATER (which is not written clearly too), then\n\n1.5ml of solution weigh 1.5g\n3% from 1.5g of solution is:\n1.5 * 3 / 100 = 0.045g = 45mg\n\nSo, solution consist 45mg of salt.

5 cc is one teaspoon so 10cc is 2 teaspoons.  a cc is also equal to a mL.  a tablespoon is 15 cc.

(5 cm^3)*(8.9)(g/cm^3) = 44.5 g

You can "guesstimate" it weighs about the same as a cubic foot of water, since most prepared food products are mostly water anyway. So, about 62Lbs, or very roughly 28 kilograms...\n\nHope that helps...

Density = 13.5 g/cm^3\n13.5 g = about .0297 pounds\n\n4/.0297= about 134.52 cm^3, or 134.52 milliliters.

I belive your u is the Greek letter mu, the prefix for micro, meaning 10^(-6).  The term ug would therefore equal 1/1,000,000 gram, which is 1/1,000 of a milligram, abbreviated mg.\n\nSo, 50mg = 50,000 ug

The answer is 50 after 10 to the 4th power dilution.\nAfter 2nd dilution (1/10 x 1/10 = 1/100), you will have c) 5,000.

the weight will be according 2 density of the material \n\nfor example for water 1  liter wighs 1 kg
