Ascientist placed 22.854 g of sodium chloride in a beaker. he then added five times as much calcium chloride as sodium chloride. finally, he divided the mixture evenly into four dishes. how much of the mixture did each dish contain? 28.5675 g 34.2810 g 137.1240 g 548.4960 g

34.2810 g

Step-by-step explanation:

Mass of sodium chloride in a beaker = 22.854 g

Mass of calcium chloride in a beaker =

Now total mass in the beaker = Mass of sodium chloride in a beaker + Mass of calcium chloride in a beaker =  22.854 g + 114.27 g = 137.124 g

Now the mixture is evenly divided into four dishes.

Amount of the mixture each dish contain =

Thus amount of the mixture in dish is 34.2810 g.

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
