Question

What should 2.00 x 10-4 L of water weigh at 29 ºC? (Show calculations and include proper units with your answer)

The Z factor (ul/mg) table

29

1.0051

Answer 1

Answer #1

Volume of water = 2.00 x 10^-4 L

Temperature T = 29°C

Z factor at 29°C = 1.0051 ul/mg

Density of water = 1/Z

= 1/1.0051

= (0.9949 mg/ul) x (10^6ul/L) x (1kg/10^6mg)

= 0.9949 kg/L

Mass of water = volume x density

= 2.00 x 10^-4 L x 0.9949 kg/L

= 1.98 x 10^-4 kg

Answer 2
