Question

Express the following SI base units using power of 10 HulaUunis
() 2.35 millimoles
(ii) 2 day
(iii) 8.45 mL
(v) 68 ug
0 0.0826 inch​

Answer 1

Answer:

1)

2.35 millimoles

we know that

1 m mole = 10^-3 mole

so

2.35 millimoles =2.35×10^-3 moles

2)

2 day = 2 × 24 hours = 48 hours = 48 × 60 minutes = 2880 minutes

          = 2880 × 60 seconds =   172800 seconds = 1.72800 × 10^5 seconds

Thus

2 days = 1.72800 × 10^5 seconds

3)

8.45 mL

Again using identity used in first part we get

8.45 mL = 8.45 × 10^-3 L

4)

68 ug

we know that

u = 10^-6

so

68 ug = 68 × 10^-6 g = 6.8 × 10^-5 g

Thus

68 ug = 6.8 × 10^-5 g

5)

0.0826 inch

We know that

1 inch = 0.0254 m

So

0.826 inch = 0.00209804 m = 2.09804 × 10^-3 m

Thus

0.826 inch = 2.09804 × 10^-3 m
