Question

Find the % of Ash if the weight of coal is 2g and after ash treatment weight of the coal is 1.02g.​

Answer 1

Answer:

which ash bro ???????????????

Answer 2

Answer:

The percentage yield of ash calculated is $51\%$.

Explanation:

Data given,

The weight of the total coal sample, W₁ = $2g$

After the ash treatment;

The weight of the coal sample residue/ash yield, W₂ = $1.02g$

The percentage yield of ash =?

Now, the percentage yield of ash can be calculated by the formula given below:

• % yield of ash = $\frac{Ash yield}{Total weight of sample}\times 100$
• % yield of ash = $\frac{W_{2} }{W_{1} }\times 100$
• % yield of ash = $\frac{1.02}{2} \times 100$ = $51\%$

Hence, the percentage yield of ash = $51\%$.
