Question

Unit conversion. 2A. Convert 862.35 torr to atm and mmHg (1 atm =760 mmHg). 2B. Convert 365.00 Liters to mL (1L = 10^3 mL). 2C. Convert 4.536 g to mg and kg (1 kg = 10^3 g, g = 10^3 mg). 2D. Convert 25.12 degree C to Kelvin. 2E. Convert 25.12 degree C to Fahrenheit (in degree F) = 9/5 T (in degree C)+ 32) 2F. Convert 1.65 m to nm (1 m = 10^9 nm). 2G. Convert 75 miles to m (1 mile = 1.6 km, 1 km = 10^3 m). 2H. Convert 2.54 m to inch (1 in = 2.54 cm, 1 m = 100 cm) 2I. Convert 2.54 gal to liters (1Gal = 3.80 L) 2J. Convert 2.54 Hz to s^-1

Answer 1

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
