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 per

erma4kov [3.2K]

Answer:

The weight percent of NaCl in the container is 21.5%

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

$weight\ \%\ of\ component\ of\ the\ solution =\dfrac{weight\ of\ the\ component\ in\ the\ solution}{total\ weight\ of\ the\ solution}\times100$

Put the value into the formula

$weight\ \%\ of\ component\ of\ the\ solution =\dfrac{168.90}{168.90+616.00}\times100$

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

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