Question

You add 168.90 grams of NaCl to a container and then you add 616.00 grams of water to that same container What is the weight percent of NaCl in the containerI​

Answer 1

The weight percent of NaCl in the container​ is 21.5%

Step-by-step explanation:

Given that,

Mass of NaCl = 168.90 gram

Mass of water = 616.00 grams

We need to calculate the weight percent of NaCl in the container​

Using formula of percentage of weight

`weight\ \%\  of\ component\ of\ the\ solution =(weight\ of\ the\ component\ in\ the\ solution)/(total\ weight\ of\ the\ solution)*100`

Put the value into the formula

`weight\ \%\  of\ component\ of\ the\ solution =(168.90)/(168.90+616.00)*100`

`weight\ \%\  of\ component\ of\ the\ solution=21.5\%`

Hence, The weight percent of NaCl in the container​ is 21.5%
