Answer:
3.75mL need to be added
Explanation:
M1 x V1 = M2 x V2
so V2=(M1xV1)/M2
(2.5Mx.015L)/2M= .01875L or 18.75ml
since we want to know how much needs to be added we subtract 18.75 from 15
Giving us 3.75ml need to be added
density(d) = mass(m) × volume(v)
given:
mass = 4.3 g = 0.0043 Kg
volume = 2.7 cm³ = 0.027 m³
= 0.0043 Kg / 0.0027 m³
= 0.15 Kg/m³
