3 Mr. Arswan prepares a mixture for a
science experiment. He measures 10.5 grams
of wood shavings, 150 grams of iron filings,
and 18.50 grams of salt. What is the total
mass of Mr. Arswan’s mixture?

To find the total mass of Mr. Arswan’s mixture, simply add up all the individual masses he measured. So, you combine 10.5 grams of wood shavings, 150 grams of iron filings, and 18.50 grams of salt. When you do the math, 10.5 + 150 + 18.50 equals 179 grams. Therefore, the total mass of the mixture is 179 grams!

In science, combining different materials and measuring their total weight can teach us about mixtures and the properties of substances. This hands-on approach not only reinforces mathematical skills but also showcases the fundamental concepts of physical science, like mass conservation and composition!
