How many grams needed from water to prepare 160 grams from potassium acetate 5 percent w?
To prepare 160 grams of potassium acetate with a 5% w/w concentration, you would need to calculate the mass of the potassium acetate in the solution. Since the concentration is given as a percentage by weight, 5% of 160 grams is 8 grams of potassium acetate. The remaining mass in the solution would be water. Therefore, you would need 152 grams of water to prepare 160 grams of potassium acetate with a 5% w/w concentration.
What is 15ww solution?
I think you may have misspelled your question. This always makes it a bit more difficult to answer. But I'm going to make the assumption that your solution was labelled "15% w/w" Is that about right? Well, then, what that means is that your solution contains 15 parts by weight of of the solute, and 85 parts by weight of the solvent. For example, a solution of 15 grams of salt and 85 grams of water is a 15% w/w solution of salt in water. By the way, w/w means "weight in weight".
What is the mass percent of acetic acid?
A home-using acetic acid solution is lesser than 10% w/w.
What is the molar mass specific heat and thermal conductivity of sae 5w 30?
The molar mass of SAE 5W-30 (which is an engine oil) depends on the specific formulation of the oil, but in general, it is a mixture of hydrocarbons with molar masses ranging from about 100 g/mol to 400 g/mol. The specific heat capacity of engine oils like SAE 5W-30 is around 2.0 to 2.5 J/g°C. The thermal conductivity of SAE 5W-30 oil is typically around 0.14 to 0.16 W/m°C.
If the equation w mg it is apparent that weight is an?
In the equation W = mg, "W" represents weight, "m" represents mass, and "g" represents acceleration due to gravity. Weight is the force exerted on an object due to gravity, and it is directly proportional to both the mass of the object and the acceleration due to gravity.
Percent Composition Molar Mass composition Molarity what has the units of g mol?
Molarity and molar are moles per litre. % comp is exactly that, just %. Mass comp seems like it would be w/w, i.e. a percentage. I have rarely heard this term but it is the closest. The answer you are looking for is molecular mass or atomic mass.
What is the density of solid metal cube2.0 cm on a side and that has a mass of 40.0 grams?
Mass = 40 gramsVolume = L x W x H = 8 cm3Density = mass/volume = 5 grams/cm3
How many grams of NaCl are needed to to make a NaCl solution 1 percent?
It depends how strong a solution you want to make. The molecular mass of NaCl is 58.44, so for a 1 molar solution you would dissolve 58.44 grams in water and make the volume up to 1 litre. For a 0.1 mol solution you'd take 5.844g to a litre, and a 2 mol solution you'd take 116.88g to a litre of water.
What is the percent by mass tungsten in the calcium tungstate compound CaWO3 commonly called scheelite?
To find the percent by mass of tungsten in calcium tungstate (CaWO₄), we first need to determine the molar masses of each component: calcium (Ca) is approximately 40.08 g/mol, tungsten (W) is about 183.84 g/mol, and oxygen (O) is about 16.00 g/mol. The molar mass of CaWO₄ is approximately 40.08 + 183.84 + (4 × 16.00) = 283.88 g/mol. The mass of tungsten in the compound is 183.84 g/mol, so the percent by mass of tungsten is (183.84 / 283.88) × 100%, which is approximately 64.8%.

Calculate the molarity of a solution of potassium permanganate and density is 1.04 gmL which contans 15.00 percent by mass?
C [mol/L] = w% * rho [g/mL] *1000 [mL/L] / (100% * M [g/mol] ) = = w% * rho [g/mL] *10 [mL/L%] / ( M [g/mol] ) = = 15.00 % * 1.04 [g/mL] *10 [mL/L%] / ( 158.034 [g/mol] ) = = 0.987 [mol/L] the molarity of the solution of potassium [in mol per liter] equals the content of KMnO4 by mass in percents multiply by density in g/mL multiply by 10 [mL/(L*%)] divide by molar mass of KMnO4 (M = 158.034 g/mol) This gives 0.987 mol/L. Thus the molarity equals approximately 1 M.
What is the molecular mass of glucose whose molecular formula is c6h12o6?
Well first you should determine the molecular mass of your glucose molecule, then you should divide the molecular mass of all the carbon by this, if I recall correctly. Should look something like (12X6) / ((6X12)+(12X1)+(6X16)) All multiplied by 100 to make it a percentage. Gives something like 40% which sounds like the right answer looking at the question.
A solid has a mass of 180 grams. What is the density?
Density is the mass divided by volume. You need to know its volume to get its density
The amount of acetylsalicylic acid in a single aspirin tablet is 325 mg yet the tablet has a mass of 2 g calculate the mass percent of acetylsalicylic acid in the tablet?
Givens for question above: If the aspirin tablet is 0.4635g. it was titrated with 18.23mL of 0.1000M NaOH to neutralize. Then 33mL of NaOH was added to hydrolyze. then it was back titrated w/13.59mL HCl. what is mass of acetylsalicylic acid? what is the percent w/w?
How do you find the density of a rectangular prism if the mass is 100 grams?
It's the mass divided by its volume. The volume of a rectangular prism is length times width times height. So it would be 100 grams divided by the volume, and that volume = (L*W*H)
What is the distance between weight and mass?
Weight is the force of gravity acting on an object, measured in newtons or pounds, while mass is the amount of matter in an object, measured in kilograms or grams. They are related through the equation W = mg, where W is weight, m is mass, and g is the acceleration due to gravity.
