Question

Two samples contain sulfur and

oxygen in the amounts shown in the
data table. What is the mass percent
of sulfur in compound B?
Sample Mass S (g) Mass 0 (g)
A
32.0
48.0
B
30.0
30.0

Answer 1

The mass percent of sulfur in compound B is 0%.

Step-by-step explanation:

To find the mass percent of sulfur in compound B, we need to calculate the mass of sulfur in compound B and divide it by the total mass of compound B, and then multiply by 100%

Mass of sulfur in compound B = Mass of compound B - Mass of oxygen in compound B

Mass of sulfur in compound B = 30.0 g - 30.0 g = 0 g

Total mass of compound B = Mass of sulfur in compound B + Mass of oxygen in compound B = 0 g + 30.0 g = 30.0 g

Mass percent of sulfur in compound B = (0 g / 30.0 g) * 100% = 0%

Answer 2

Sample A=40 Sample B=50

Step-by-step explanation:

32+48=80

32/80x100=40

The 100 is to convert it to a percentage

Sample B

same thing

30+30=60

30/60x100=50
