Question

Use the exponential notation to express the physical quantities

a. V= 15. 50 ml to L


b. M= 5. 00mg to g


c. M= 2000 to g


d. Λ= 256. 4nm to m

Answer 1

a. V = 0.01550 L (or 1.550 x 10^-2 L)

b. M = 0.00500 g (or 5.00 x 10^-3 g)

c. M = 2.000 kg (or 2.000 x 10^3 g)

d. Λ = 2.564 x 10^-7 m (or 2.564 nm)

Answer 2

a. V = 15.50 ml = 0.01550 L (since there are 1000 ml in 1 L)
Therefore, V = 1.550 x 10^-2 L (expressed in exponential notation)

b. M = 5.00 mg = 0.00500 g (since there are 1000 mg in 1 g)
Therefore, M = 5.00 x 10^-3 g (expressed in exponential notation)

c. M = 2000 g
Therefore, M = 2.00 x 10^3 g (expressed in exponential notation)

d. Λ = 256.4 nm
Since there are 10^9 nm in 1 m, we can convert Λ to meters as follows:
Λ = 256.4 x 10^-9 m
Therefore, Λ = 2.564 x 10^-7 m (expressed in exponential notation)
