Molarity = moles of solute/Liters of solution

3 M KBr = moles KBr/1 liter

= 3 moles KBr (119 grams/1 mole KBr)

= 357 grams needed

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

How do you prepare 0.1n hypona2s2o4?

Let me translate the question: I think you are asking how to make a 0.1 molar solution of Na2S2O4. Molarity is moles of solute divided by liters of solution. To make this easy, let's assume you want to make one liter of the solution. That means you need to dissolve in 0.1 moles of Na2S2O4 into one liter of water to make a 0.1 molar solution. The formula weight of Na2S2O4 is 174.1 grams per mole so 0.1 moles of it is 17.41 grams. Therefore you would need to dissolve 17.41 grams of Na2S2O4 into one liter of water to make a 0.1 molar solution.

How do you make 1 molar solution of glucose?

A 1 molar solution by definition is 1 mole of something, in this case glucose, in 1 liter of solution. The molecular weight of something can be found on the perdiodic table. The weight listed on the periodic table is the grams in a mole, these of course are for atoms. 12 H + 6 C +6O + 188.1558 grams in a mole of glucose. Put this weight into one liter of water.

How do you prepare 1 molar iodoacetamide solution?

What volume do you want to make. To make 1 liter, you take the 185 g (the molar mass) and dissolve in enough solvent to make the final volume 1 liter.

How do you prepare 0.01 m edta solution?

Dissolve 2.92 grams edta in one liter distilled water. The molar mass of edta is 292.24 g mol-1. Molarity is moles of solute divided by liters of solute. To make a 0.01m solution, take 0.01*the molar mass of the substance and dissolve it in one liter of water. So: 0.01*292.24=2.92 grams.

How do you make a 10 percent acetic acid solution from a 2 Molar solution?

10 percent acetic acid indicates there is .1 liters of acetic acid, which is equal to 1.75 moles, or 105 grams per liter. To make this solution, add 7 liters of the 2M solution to 1 liter of water, or 7/8 solution to 1/8 water.

How do you prepare solutions when given the molar concentration?

In addition to the molar concentration, you need to know the volume of solution desired and the molar mass (gram/mole) of the substance. Then, molar concentration = mole/liter and with the known volume, you calculate as follows:mole/liter x liter x gram/mole = grams. Measure out the calculated grams and dissolve in enough solvent to make the final volume.

How many grams of KCl are needed to make 3.0 L of a 3.4 M solution?

In a 3.4 M solution, there are 3.4 moles per liter. If you want to make 3 liters of solution, you'll need 3 liter * 3.4 moles/liter = 10.2 moles The molar mass of KCl is 39.098 g/mole K + 35.453 g/mole Cl = 74.551 g/mole KCl To get the number of grams, multiply the number of moles by the molar mass: 10.2 moles * 74.551 g/mole KCl = 760.4202 g = 0.760 kg
