keeping with the same unit fractor harry is correct.\n \n .2 ml

Going from 10^12 cells/mL to 10^10 is a 1:100 dilution.\nIf you want a final of 2mL, you need to add 20uL of your stock solution.\nSo do 20uL of stock (10^12)+ 1980uL of salt solution = 2000uL (10^10), which is the same as 2mL.

too little\n\n0.25 liters = 250 milliliters\n\nyou need to add 50 milliliters more\n\nwhich 50 milliliters = 0.05 liters

It kind of depends on what you are starting with but lets say that you have a solution of drug containing a concentration of 20 milligrams per milliliter and you are running it at 2 milliliters per hour.  You need to multiply it out to convert the units.  If you are starting with 20 mg/mL at 2 mL/hour, first you convert hours to minutes and then you convert mg to micrograms.  The mL cancel, the mg cancel, the hours cancel, and the units you are left with are micrograms per minute!\n\n__20 mg___  x   __2 mL___  x  ___1 hour___ x _1000 mcg__ =\n1 mL             1 hour         60 minutes    1 mg\n\nThere are other ways to do it, but I find this the easiest.  If you need to figure out mcg/kg/minute, you just divide the last number by the patient's weight.

0.150 M NaOH\n\n0.150mol / L  X  40 g / mol  X  1 L / 1000 mL  X  200 mL  =  1.2 grams of solute (NaOH)

30 milliliters is equal to 0.03 liters\n30 milliliters is equal to 0.01 gallons \n30 milliliters is equal to 1.01 ounces in the US conversion\nor\n30 milliliters is equal to 1.06 ounces in the British conversion\n\nheres the site to make sure i was right\nhttp://www.sciencemadesimple.net/volume.php

Use the equation M1V1 = M2V2\n\nM1 is the molarity of the HCL or 9.9 M\n\nV1 is the first volume of 102 ml but it needs to be changed to Liters. So it is 0.102L\n\nV2 is the total volume of the final solution so 525 ml (0.525 L) + V1 or 0.102L = 0.627\n\nM2 is what you are looking for - the final concentration or molarity.\n\nRearrange the equation to ((M1)(V1)) / (V2)  = M2\n\n(0.102L)(9.9M) / (0.627) = 1.61 M\n\nHope this helped!

480,000.0 mg /1000 = 480g, 0.80 L x 1000 = 800 ml, so 480g/800ml.  divide both sides by 800 = 0.6g/ml. m = milli = 1/1000. 1000 mL = 1 L, 1000 mg = 1g, 1000 meter = 1 kilo meter. Kilo = 1000.

Here is a tip.  Whenever you have a question like this just go to Google's search engine.  Your question can then be typed as "1 mcg in mg" in the search box.\n\nInstead of searching for websites, google does the conversion for you.  This is one of many secret tools you can use on Google.\n\nThe answer Google gives is this: 1 mcg = 0.001 milligrams

The convertion is with reference to a certain medium...\n\nIf the medium is ordinary fresh WATER ...\n\n1 gram (gm.) = 1 millilitre (ml.)\n\n1,000 milligram (mg.) = 1 gm.\n\nTherefore:\n\nIt will take 1,000 mg. to produce 1 ml. of water.\nIt will take 1,000 gm. to produce 1 liter of water.

FW of NaCl is 58.44  then\n\n   58.44 gm in 1000 mL = 1 Molar\n\n   4.78  gm in 200 mL = ?\n\ndo cross multiplication\n\n(4.78 gm x 1000 mL x 1 M) / (58.44 gm x 200 mL) = 0.4089 M\n\n(gm/gm and mL/mL cacels out so you get answer in M)\n\n\nNow you are taking 28 mL of 0.4089 M solution and diluting it to make final volume of 100.  Use M1V1 = M2V2\n\n0.4089 M x 28 mL = ? x 100 mL\n\n\nThen  ? = (0.4089 M x 28 mL) / 100 mL    { mL/mL cancels out and you get answer in Molarity)\n\n\n? = 0.1145 Molar is your answer

1 mL (millileter) = 1 E-3 Liters\n\n1 ML (MegaLiter) = 1 E6 Liters\n\n1 E6 / 1 E-3 = 1 E9,\nSo there are 1 E9 mL per 1 ML, or\n1,000,000,000 mL / ML.
