1.00 L Express your answer using three significant figures.

1800 mL Express your answer using two significant figures

10.5 L Express your answer using three significant figures.

54.0 mL Express your answer using three significant figures.

Answer 1

we will use charts low, which states that At constant pressure, the volume of gas is directly propostional to Kenin temperatur Whose = Initial tolume = 4.10L I & Initial temp = 0°c = 0+273 = 273k 2 - Final wolume; T2 = Final temperature U₂ = 1 4.10L IL 273k +2 273 2 x 1L 4.10 I 66k 66.58k. 66.58 K – 273 k-206.41°C] Vi= 1800 mL - 1800/1000 = 1.800 273k X1.800L 491-4K L T2 = = 119.85k! 4.10 L 4.10L 119.85 - 273 K = - 53 °C
