Slide 1 - Slide
Opdracht 4
V = 0,85 l p = 2,5 g/cm3
massa in gram
Slide 2 - Slide
Opdracht 4
V = 0,85 L p = 2,5 g/cm3
massa in gram
m = V x p
m = 850 x 2,5
m = 850 x 2,5 = 2125
m = 850 x 2,5 = 2125 g
0,85 L = 850 mL
850 mL = 850 cm3
Slide 3 - Slide
Opdracht 9
m = 138 kg V = 159 L
Dichtheid in kg/L
Slide 4 - Slide
Opdracht 9
m = 138 kg V = 159 L
Dichtheid in kg/L
p = m : V
p = 138 : 159
p = 138 : 159 = 0,87
p = 138 : 159 = 0,87 kg/L
Slide 5 - Slide
Opdracht 10
100 - 40 = 60 (percentage roet)
10,8 x 0,6 = 6,48 g
Slide 6 - Slide
Opdracht 11
m = 22,8 g V = 23,5 cm3
Dichtheid in g/cm3
p = m : V
p = 22,8 : 23,5
p = 22,8 : 23,5 = 0,97
p = 22,8 : 23,5 = 0,97 g/cm3
Slide 7 - Slide
Slide 8 - Slide
Opdracht 18
p = 800 g/L V = 15000 L
m van beide wagons
m = p x V
p = 800 x 15000
p = 800 x 15000 = 12 000 000
p = 800 x 15000 = 12 000 000 g = 12 000 kg
Slide 9 - Slide
Opdracht 18
p = 800 g/L V = 15000 L
m van beide wagons
m = p x V
p = 800 x 15000
p = 800 x 15000 = 12 000 000
p = 800 x 15000 = 12 000 000 g = 12 000 kg
12 000 x 2 = 24 000 kg
