What is the molarity of a solution containing 17.0g of nh3 in 2.0 L of solution?
liq [111]
To find molarity use the following formula

molarity= moles/ liters

first, we need to calculate the moles using the grams of NH₃. remember to convert grams to moles, you need the molar mass of the molecule which you can determine by adding the mass of each atom

molar mass of NH₃ = 14.0 + (3 x 1.01)= 17.03 g/ mol

now, let convert grams to moles

17.0 g (1 mol/ 17.03 grams)= .998 moles NH₃

now, we can plug in these values to solve for molarity

molarity= 0.998 mol/ 2.0 Liters= 0.50 M (the answer is a)

How to find weight with volume and density ​
stira [4]

Answer:

Explanation:

Look up the density of the material the object is made of in kg/m³.

Measure the volume of the object in m³.

Multiply the density by the volume.

You will then have the mass of the object in kg.

A sample of gas occupies a volume of 73.7 mL. As it expands, it does 133.7 J of work on its surroundings at a constant pressure
katen-ka-za [31]
In thermodynamics<span>, </span>work<span> performed by a system is the energy transferred by the system to its surroundings. It can be calculated by the expression:
</span>
W = PdV

Integrating,

We will have,

W = P(V2 - V1)
133.7 (1 litre-atm / 101.325 Joule) ( <span>760 Torr / atm ) </span>= 783 (V2 - .0737 )
V2 = 1.35 L

Hope this answers the question.  Have a nice day.
