Question

What volume of a liquid will contain 4 mol? Molar mass of liquid is 280 and its density is 1.4 g/mL
(a) 0.4 L
(b) 1.6 L
(c) 0.8 L
(d) 48 x 1023

Answer 1

Answer:

0.8 L

Explanation:

Molar mass of liquid, m = 280g

Density of liquid = 1.4g/mL

we know that Volume = Mass/density

so, Molar volume of liquid,V = 280g/1.4g/mL

V = 200 mL

we know that 1 litre = 1000 mL

so Molar volume of liquid, V = 0.2 L

Now volume of 4 moles of liquid = 0.2*4 = 0.8 L
