If you obtain 3.0 grams of aspirin from an experiment that could make no more than 3.14 grams, what is the percent yield?

Masteriza [31]

Answer:

96%

Explanation:

To find the percent yield, we can use this equation

$\frac{Actual}{Theoretical} *100$

The actual yield of aspirin is 3.0 and the theoretical is 3.14 in this case, so just plug the numbers in.

$\frac{3.0}{3.14} *100\\\\ =96$

Thus the percent yield is 96%

What is the molar mass of 81.50 g of gas

garik1379 [7]

The molar mass of gas = 238.29 g/mol

<h3>Further explanation</h3>

Given

mass = 81.5 g

P=1.75 atm

V=4.92 L

T=307 K

Required

molar mass

Solution

The gas equation can be written

$\large{\boxed{\bold{PV=nRT}}$

$\tt n=\dfrac{mass}{molar~mass}$

So the equation becomes :

$\tt Molar~mass=\dfrac{mRT}{PV}$

Input the value :

$\tt M=\dfrac{81.5\times 0.082\times 307}{1.75\times 4.92}\\\\M=238.29~g/mol$
