Explanation / Answer

2A)

Given P = 862.35 torr

1 torr = 0.001316 atm

then

862.35 torr = 0.001316 x 862.35 atm = 1.135 atm

1 atm = 760 mmHg

then

1.135 atm = 760 x 1.135 mmHg = 862.49 mmHg

2B)

365.00 L to mL

1 L = 103 mL

then

365 L = 365 x 103 mL = 365000 mL

2C)

4.536 g to mg and Kg

1 g = 103 mg

then

4.536 g = 4.536 x 103 mg = 4536 mg

1 Kg = 103 g

then 1 g = 10-3 Kg

so 4.536 g = 4.536 x 10-3 Kg = 0.0045 Kg

2D)

25.12 0C to Kelvin

We know that 0 0C = 273.15 K

then

25.12 0C = 25.12 + 273.15 = 298.27 0C
