Question

Calcule a densidade das substâncias a)m=2,0 g; v=10mL b)m=50 g; v=25cm3 c)m=10 g; v=10cm3​

Answer 1

a)m=2,0 g; v=10mL => d=2/10= 0,2g/ml

b)m=50 g;v=25cm3=> d=50/25 =2g/cm³

c)m=10 g; v=10cm3=> d=10/10 =1g/cm³

Answer 2

d= m/v

a) d= 2/0.01

d = 200 g/L

b) d= 50/0,01

d = 5.000 g/L

c) d= m/v

d= 10/0,01

d= 1.000 g/L
