Question

What is the volume of 90.0 grams of ether if the density of ether is 0.70 g/mL?

a)1.1 x 10^2 mL
b)1.3 x 10^2 mL
c)6.3 x 10^1 mL
d)7.8 x 10^-3 mL

Answer 1

b) 1.3 E2 mL

Step-by-step explanation:

• density = mass / volume

∴ m = 90.0 g

∴ density = 0.70 g/mL

⇒ V = m / d

⇒ V = 90.0g / 0.70 g/mL

⇒ V = 128.571 mL

⇒ V = 1.285 E2 mL ≅ 1,3 E2 mL
