<span>1) Balanced chemical equation

Sb2S3(s) + 3Fe(s) --> 2Sb(s) + 3FeS(s)

2) Theoretical molar ratios

1 mol SbsS3 : 3 mol Fe : 2 mol Sb : 3 mol FeS

3) Convert </span><span>18.45g Sb2S3 and12.1g Sb to moles

You need to use the atomic and molar masses

Sb: 121.76 g/mol

S: 32.07 g/mol

Sb2S3: 2 * 121.76 g/mol + 3 * 32.07 g/mol = 339.73 g/mol

18.45 g Sb2S3 / 339.73 g/mol = 0.0543 mol Sb2S3

12.1 g Sb / 121.76 g / mol = 0.099 mol Sb

Theoretical yield:

1 mol Sb2S3 / 2 mol Sb = 0.0543 mol SbsS3 / x mol Sb

Solve for x:

x = 0.0543 mol Sb2S3 * 2 mol Sb / 1 mol Sb2S3 = 0.1086 mol Sb

4) Percent yield

0.099 mol Sb / 0.1086 mol Sb * 100 = 91.16%

Answer: 91.5% (the difference with 91.16% is due to the decimals used for the atomic masses)

Which unit abbreviation is a measurement of force?
Artemon [7]
So,

Recall Newton's Second Law of Motion: force = mass x acceleration

Also recall:

acceleration = velocity/time
velocity = distance/time

Distance is expressed in meters.
Time is expressed in seconds.
Mass is expressed in kilograms.

v = m/s
a = m/s^2
F = m * a
F = kg * m/s^2

F= \frac{kg*m}{s^2}

The unit for force is the Newton (N).

How many moles of sodium hydroxide are there in 1.0mL of 2.0M NaOH
kvasek [131]
To find the moles, you can use the following formula

moles= Molarity x Liters

Molarity= 2.0 M
Liters= 0.0010 Liters  ---------------->>>>>>>>>> 1.0 mL= 0.0010 Liters

moles= 2.0 M x 0.0010 Liters= 0.0020 moles
