Answer:

m_{solute}=100g

Explanation:

Hello,

In this case, by considering the mathematical definition of by mass percentage of a solute as shown below:

\%m/m=\frac{m_{solute}}{m_{solution}}*100\%

We are able to compute the mass of the solute in a 20% solution having 500 g of solution as follows:

m_{solute}=\frac{m_{solution}*\%m/m}{100\%} =\frac{500g*20\%}{100\%}\\ \\m_{solute}=100g

Best regards.

when a number in scientific notation contains a significant zero, is that zero also significant in the expanded notation? give t
AlexFokin [52]
I believe you are referring zero as the exponent. <span>Any number (except 0) with exponent 0 is defined to mean 1.
</span>

For one thing, there is a rule: 

<span> a^m/ a^m = a^m-m = a^0

</span>But (when a is not equal to <span>0),
</span>
a^m/ a^m = 1

Therefore, we must define a^0 as 1.
