1. convert each of the following measurements to the SI base unit... the equal sign after the problems illustrates my answer that I got from doing the problems myself. can someone very if I got the answer right, and if not explain why and the process of getting the right answer

45mg=.045



125ns=.0000125
10.7ul=.0000107
12.53456kg=12,534.6

Answer: The conversions are given below.

Step-by-step explanation:

Unit is defined as the quantity that is used as a standard for measurement.

S.I unit of mass if kilograms.

S.I unit of time is seconds.

S.I unit of volume is cubic meters.

The given conversions are not correct.

  • For Option 1: 45 mg

Converting this into kilograms, we use the conversion factor:


1kg=10^(6)mg

So,
45mg* ((1kg)/(10^6mg))=0.000045kg

Hence, the correct value is 0.000045 kg

  • For Option 2: 125 ns

Converting this into seconds, we use the conversion factor:


1s=10^(9)ns

So,
125ns* ((1s)/(10^9ns))=0.000000125s

Hence, the correct value is 0.000000125 ns

  • For Option 3:
    10.7\mu L

Converting this into cubic meters, we use the conversion factor:


1m^3=10^(9)\mu L

So,
10.7\mu L* ((1m^3)/(10^9\mu L))=0.0000000107m^3

Hence, the correct value is
0.0000000107m^3

  • For Option 4: 12.53456 kg

The given value is already in its S.I unit.

Hence, the correct value is 12.53456 kg
