Question

convert the following measurements as indicated a. 95 cm to meters B. 1.1 L to ml c. 17000 M to km D. 500 kg to grams e. 2.55 milliemol to moles

Answer 1

a.

100 cm is equal to 1 m, then 95 cm in metres is given by the following expression,

`95 cm = (95 cm * 1 m)/(100 cm) = 0.95 m` (unitary method)

b.

1 l is equal to 1000 ml, then 1.1 l in millilitres is given by the following expression,

`1.1 l = (1.1 l * 1000 ml)/(1 l) = 1100 ml` (unitary method)

c.

1 km is equal to 1000 m, then 17000 m in kilometres is given by the following expression,

`17000 m = (17000 m * 1 km)/(1000 m) = 17 km` (unitary method)

d.

1 kg is equal to 1000 gm, then 500 kg in grams is given by the following expression,

`500 kg = (500 kg * 1000 g)/(1 kg) = 500000 g` (unitary method)

e.

1 mole is equal to 1000 millimoles, then 2.55 millimoles in moles is given by the following expression,

`2.55 millimoles = (2.55 * 1 )/(1000) = 0.00255 moles` (unitary method)
