A student found thet her mixture was 15 percent NH4cl 20 percent NaCl and 75 percent Sio2 Assuming her caculations are correct what did she most likely do incorrectly in her experiment?

Answer 1

This student has 15 percent, 20 percent, and 75 percent of something. Her calculations do not add up to 100%.

Answer 2

The student most likely mistakenly swapped the percentages of NaCl and SiO2 in her calculations. She likely misinterpreted the data or made an error in transposing the numbers during the calculations.
