Question
What is the % by mass of a mixture containing 15.89 grams of salt dissolved in 677 grams of water?
Solution
To find the percent by mass of the salt in the mixture, you can follow these steps:
-
First, find the total mass of the mixture. This is the sum of the mass of the salt and the mass of the water. So, 15.89 grams (salt) + 677 grams (water) = 692.89 grams (total mass).
-
Next, calculate the percent by mass of the salt. This is the mass of the salt divided by the total mass of the mixture, multiplied by 100% to convert the decimal to a percentage. So, (15.89 grams / 692.89 grams) * 100% = 2.29%.
So, the percent by mass of the salt in the mixture is 2.29%.
