You know the molarity and you know the volume. First off you find the moles. Molarity divided by 1000, multiplied by the volume in cm^3. Then you multiply the moles by the molecular mass of the solute, to get the weight in grams.

The units of molarity are moles solute/liters of solution. It can also be expressed as moles of solute/dm 3 . (This means the same thing) These are both units of measurement which express the concentration of a given solution. Molarity unit: M

In the equation for molarity which is M=n/V where M is the molarity, the n is # of moles of solute and V is the measure of solution in Liters(L). Therefore for this question the answer is 2M

The total number of moles of a solute, regardless of state, in one liter of solution. Given as moles/L.

Length, diameter and radius are measured in centimeters. Surface area is measured in square centimeters. Volume is measured in cubic centimeters.

This cannot be answered as written. Molarity is defined as moles of solute per liter of SOLUTION. There is no way to calculate the volume of the entire solution when given the mass of the solvent. You need to measure the volume of the solution (in litres) after it has been made at room temperature and then just divide.molarity = moles / liters of solution

The molarity of a solution is the amount of substance in a given amount of solute. The units are usually given as moles per liter (or dm3). As such, for each liter you have 0.5 moles of substance (2 divided by 4), so it's a 0.5 molar solution.

Molarity is the no of moles of solute dissolved per litre of a solution. now if u want to find it from the percentage purity , here is the formula for that Molarity = % purity x density x 10 ___________________ molar weight of the solute note : density is usually given %purity problems, if its not u can evualvate it from from formula { d= mass/volume} i hope it solves the problem

The amount of solute per a given amount of solvent is called the concentration; if it is expressed in terms of moles per liter (which is what chemists usually work with) then it can also be called molarity.

4 cubed = 64. So the cube is 4x4x4.Answer:We know that the volume of a cube = Side3 cubic centimeters.Given that the volume of the cube is 64 cubic centimeters.We need to find the dimensions of the cube.Side3 = 64Side3 = 43Side = 4 centimeters.Source:

The conversion between cubic m and cubic cm are given .On finding the relation we get as follows . 1 cubic m =1000000 cubic cm . 8 cubic m =8000000 cc.

Reminds me of the ___ staring intently at a can of frozen orange juice in the supermarket... The can said "Orange juice concentrate". The term you are looking for is "Concentrated solution" or "Solution concentration". Molarity, "In chemistry, molar concentration (also called molarity, amount concentration or substance concentration) is a measure of the concentration of a solute in a solution, or of any molecular, ionic, or atomic species in a given volume." ---->

Molar mass of HNO3 =63g Given mass= 12.6g No. of moles=12.6/63=0.2 moles Molarity= No. of moles/Volume of solution(in litre) = 0.2/0.5=0.4 M

for unit of volume .The conversion between cubic cm and l is given as follows. we can say that, 1 l =1000 cc.

Cubic centimeter or cm3 is a measurement of volume. To find volume in cm3, you need to have three dimensions, such as length, width and height for a cube given in centimeters. By multiplying these three measurements, you find the volume in cubic centimeters.

Molarity is moles/liter. From moles/liter, you can calculate mass in grams by converting the moles to grams using molar mass, and then use the volume to calculate the final mass in that volume. Thus,moles/liter x gram/mole x liters = mass in grams

What are those numbers ? Are they the length, width, and height of a rectangular prism ? If they are, then its volume is 132 cubic centimeters. If they're not, then there's no way to answer the question with the given information.

Here is the information you are given and a corresponding equation demonstrating the relationship between the given information and the unknown. Vtotal = Vwater + Vsand = 42cm3 Here is the given equation rearranged (by subtracting the volume of water from both sides) to target the unknown information (volume of sand). Vsand = Vtotal - Vwater Plugging in the given info to the equation yields your answer. Vsand = 42 - 20 Vsand = 22cm3

What are those numbers ? Are they the length, width, and height of a rectangular prism ? If they are, then its volume is 132 cubic centimeters. If they're not, then there's no way to answer the question with the given information.

This question would have been a lot more fun to work onif the area of the base had actually been given . . .

Volume = mass / specific gravity. Units are cubic centimeters and grams or cubic meters and tonnes. s.g. has no units : it is a dimensionless quantity.

Given that water density is approximately 1000 kg/m^3 = 1 kg/dm^3, and 100 cm^3 = 0.1 dm^3, The mass of 100 cubic centimeters of water is about 100 grams.

The amount of solute needed to dissolve a given amount of solvent depends on the specific solute and the specific solvent.

Thanks to some jokester I have to do this answer all over again. I hate that about this site. Anyone can but in! Perhaps you will be given atoms of the compound. 3.42 X 10^22 atoms carbon (1 mole C/6.022 X 10^23) = 0.057 moles Carbon -----------------------------or, you will be given, Molarity and Liters of solution Molarity = moles of solute/Liters of solution Moles of solution = Molarity * Liters of solution -------------------------------------------------------------there are two ways without mass of element/compound If that is not what you meant put a message on my message board.
