Explanation / Answer

1. 1 mL = 1x10-3 L

Therefore option (C) is correct

2 . 1TB = 1012 bytes

Therefore option (D) is correct

3.We know that Mass = Volume x density

(A) mass = 1000 mL x 1.0 (g/mL) = 1000 g

(B) mass = 1000 cm3 x(1mL/cm3) x 1.0 (g/mL) = 1000 g

(C) mass = 2L x (1000 mL/L) x 1.0 (g/mL) = 2000 g

(D) mass = 1000 g

So 2L water having more mass

Therefore option (C) is correct.

4.Sodium is an alkali metal

So option ( A) is correct
