Question 1

% of concentration means what?

Answer 1

g/100mL

Question 2

1:1,000 means what

Answer 2

1g/ 1,000mL

Question 3

to convert from % to mg/mL what do u do

Answer 3

move decimal point one place to the right

ex 2% = 20mg/ml 3%= 30mg/mL 0.9%= 9mg/mL

Question 4

to convert 1:100,000, 1:500,000 to mcg/mL what do you do?

Answer 4

divide denominator by 1,000,000
ex 1:100,000 = 10mcg/ml (also if you keep the same and do it divided to 1,000 it will give u g/mL then you can convert that into mcg/mL)
ex 1:100,000 = 0.01g/mL then move decimal for mcg 10mcg/mL either way works

Question 5

Answer 5

10 mg to mcg

move the decimal 3 spots to the right 10,000 mcg

Question 6
