SET 2: Question 1 of 10
How many g are there in 0.75 kg?
Type in all zeros, eg 0.00000673
g
There are 750 g in 0.75 kg.
1 kg = 103g
Thus: 0.75 kg = 0.75 x 1000 g = 750 g
No, that is not the correct answer.

SET 2: Question 2 of 10
How many kg are there in 80 g?
Type in all zeros, eg 0.00000673
There are 0.08 kg in 80 g.
1 kg = 103g
Thus: 80 g = 80 / 1000 kg = 0.08 kg

SET 2: Question 3 of 10
How many mg are there in 5 g?
Type in all zeros, eg 0.00000673
There are 5000 mg in 5 g.
1 mg = 10-3g
1 gram is 100 times ie 103 times larger than a milligram
10-3
Thus: 5 g = 5 x 1000 mg = 5000 mg
No, that is not the correct answer.

SET 2: Question 4 of 10
How many µg are there in 0.25 g?
Type in all zeros, eg 0.00000673
There are 250000 µg in 0.25 g.
1 µg = 10-6g
1 gram is 100 times ie 106 times larger than a microgram
10-6
Thus: 0.25 g = 0.25 x 1000000 µg = 250000 µg
No, that is not the correct answer.

SET 2: Question 5 of 10
How many ng are there in 0.5 g?
Type in all zeros, eg 0.00000673
There are 500000000 ng in 0.5 g.
1 ng = 10-9 g
Thus
1 gram is 100 times ie 109 times larger than a microgram
10-9
Thus: 0.5 g = 0.5 x 1 000 000 000 ng = 500 000 000 ng
No, that is not the correct answer.

SET 2: Question 6 of 10
How many pg are there in 0.01 g?
Type in all zeros, eg 0.00000673
There are 10 000 000 000 pg in 0.01 g.
1 pg = 10-12g
Thus:
1 gram is is 100 times ie 1012 times larger than a picogram
10-12
Thus: 0.01 g = 0.01 x 1 000 000 000 000 pg = 10 000 000 000 pg
No, that is not the correct answer.

SET 2: Question 7 of 10
How many g are there in 100 mg?
Type in all zeros, eg 0.00000673
There are 0.1 g in 100 mg.
1 mg = 10-3g
1 milligram is 100 times ie 103 times smaller than a gram.
10-3
Thus: 100 mg = 100 / 1000 g = 0.1 g
No, that is not the correct answer.

SET 2: Question 8 of 10
How many g are there in 7000 µg?
Type in all zeros, eg 0.00000673
There are 0.007 g in 7000 µg.
1 µg = 10-6g
Thus:
1 microgram is 100 times ie 106 times smaller than a gram
10-6
Thus: 7000 µg = 7000 / 1000000 g = 0.007 g
No, that is not the correct answer.

How many g are there in 10000 ng?
Type in all zeros, eg 0.00000673
There are 0.00001 g in 10000 ng.
1 ng = 10-9g
Thus:
1 nanogram is 100 times ie 109 times smaller than a gram
10-9
Thus: 10000 ng = 10000 / 1 000 000 000 g = 0.00001 g
No, that is not the correct answer.

How many g are there in 5000 pg?
Type in all zeros, eg 0.00000673
There are 0.000000005 g in 5000 pg.
1 pg = 10-12g
Thus:
1 picogram is 100 times ie 1012 times smaller than a gram
10-12
Thus: 5000 pg = 5000 / 1 000 000 000 000 g = 0.000 000 005 g
No, that is not the correct answer.
