Question

1. calculate moles of acid assuming the sample is diprotic for two trials that were used.

trial 1
0.0862999989/mol
trial 2
0.3800304999/mol

1. calculate the molar mass of the diprotic acid for two trials that were used.

trial 1
1.274623436
trial 2
0.147068932

1. calculate the average molar mass of the diprotic acid.

Explanation:

Step1: Recall average formula

The formula for the average of two numbers $x_1$ and $x_2$ is $\bar{x}=\frac{x_1 + x_2}{2}$.

Step2: Identify values

Let $x_1 = 1.274623436$ (molar - mass from Trial 1) and $x_2=0.147068932$ (molar - mass from Trial 2).

Step3: Calculate average

$\bar{x}=\frac{1.274623436 + 0.147068932}{2}=\frac{1.421692368}{2}=0.710846184$

Answer:

$0.710846184$
