c) 13,6053 g/cm3...
d)136,054 g/cm3

jwbnya cpet ya..pliss

Answer 1

Verified answer

To = 8 °C
T = 30 °C
p0 = 13,6 g/cm^3 = 13.600 kg/m^3
μ = 18 x 10^-6/°C

p = p0(1 + μ(T-To))
p = 13.600(1+((18x10^-6)(30-8))
p = 13.600 (1 + 396 x 10^-6)
p = 13.600(1,000396)
p = 13.605,3 kg/m^3
p = 13,6053 g/cm^3
