Apatient needs to be given exactly 1000ml of 15% (w/v) intravenous glucose solution. the stock solution is 35% (w/v). how many milliners of the stock solution are needed to prepare the fluid for the iv bag? ?

Given:

Concentration of glucose stock solution, C1 = 35% (w/V)

Concentration of intravenous glucose, C2 = 15 %

Volume of intravenous glucose, V2 = 1000 ml

To determine:

The volume of stock solution needed, V1

Explanation:

Use the relation-

C1 * V1 = C2 * V2

V1 = C2*V2/C1 = 0.15 * 1000/0.35 = 428.6 ml

Ans: Volume of stock solution needed is around 428.6 ml

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
