The new concentration of the KCl solution after mixing 1 L new volume is 0.28 M.

<h3>How do we calculate the concentration?</h3>

Concentration in terms of molarity will be calculated by using the below equation as:

M₁V₁ = M₂V₂, where

M₁ = molarity of old KCl solution = 1.6 M

V₁ = volume of old KCl solution = 175 mL = 0.175 L

M₂ = molarity of new KCl solution = ?

V₂ = volume of new KCl solution = 1 L

On putting all these values on the above equation, we get

M₂ = (1.6)(0.175) / (1) = 0.28 M

Hence resultant concentration is 0.28 M.

How many grams of aspartame (C14H18N2O5), also known as Nutrasweet, contain 1.98×1021molecules of aspartame?
Umnica [9.8K]

Answer:

0.97 grams

Explanation:

number of molecules=no of moles × Avogadros number

so

number of moles=nu.of molecules ÷ 6.02×10power23 = 1.98×10power21 ÷ 6.02×10p23=0.0033 mol

mass=nu.of moles× molar mass

molar mass of aspartame=

(14×12)+18+(2× 14.0067n)+(5×16)=294.0134 u

mass = 0.0033 ×294.0134 =0.97 gram

Which statement is true?
AleksandrR [38]

Exothermic reaction is where there is release of energy during a reaction

The enthalpy of exothermic reaction is negative

The relation between energy of products, reactants and enthalpy of reaction is

Enthalpy of reaction =  sum of enthalpy of formation of products - sum of enthalpy of formation of reactants .

As enthalpy of reaction is negative, it means the enthalpy of products is less than the enthalpy of reactants  so answer is :

In an exothermic reaction the energy of the product is less than the energy of the reactants.

How many moles of NaCl are needed to make 10.0L of a 5 M solution of<br> Salt water?*
vesna_86 [32]

Answer: 50 mol

Explanation:

Molarity=\frac{Moles -of -solute}{liters -of -solution}

M=\frac{mol}{L}

mol=M*L
