magnesium oxide, mgo, is 60.3% magnesium. how much magnesium is contained in a 25.5 g sample of magnesium oxide?\n6.03 g\n4.25 g\n10.1 g\n15.4 g
Answer
Explanation:
Step1: Identify the percentage - mass formula
The mass of magnesium in the sample can be found using the formula: Mass of magnesium = Percentage of magnesium×Mass of magnesium oxide sample.
Step2: Convert percentage to decimal
60.3% = 0.603.
Step3: Calculate the mass of magnesium
Mass of magnesium = 0.603×25.5 g. [0.603\times25.5 = 15.3765\approx15.4] g
Answer:
15.4 g
